You have obviously missed threads then, both in this forum, as well as in Bullroarer forum. Some threads had like 200 posts in them. Page after page with people not happy. I can assure You that it was not the same 3-4 in each post but alot of different players. I have never seen such an overwhelming majority be against upcoming changes as they have in this latest update. In facts it has been the same 5-6 people that has tried to say all is good. About anything from lootboxes and the other changes, while most (the vast majority of those posting here that is) have acctually been against those things. Last time I saw such a big % of the playerbase dislike something was over Mounted Combat and before that Radiance a while after Moria release until and through Mirkwood. Before it was finally removed. It was alot more players back then but % wise it is similar to how many have been disliking this update and the whole LoE/Ash gear progression system once they realized it will be an insane grind to get any gear of value with all the things being removed, changed and put behind 1-day locks etc, in this update.
And if You think it's just 3-4 players in LoTRO that are not happy about the whole lootbox siutation You muts have been living under a rock for the last few weeks or in a bubble. EA had the most down voted post in Reddits history. Over 600.000 down votes in less than a week. Before that the most disliked comment ever had like 30.000 down votes. Star Wars: Gamblefont II has sold really badly and EA's stocks have now gone down like 6-9%. All because of their lootbox controversy. Disney even called them and told them to remove selling lootboxes for money in-game until further notice and they did. You will find tons of petitions, articles and videos out there to stop lootboxes in games or at least get regulations on them. Like age-restriction of the games containing lootboxes. Gambling license and regular controls to check that the system isn't rigged in games. All to protect consumers as many feel they are being hustled. No way to even know if codes are for example made so that the item Your specific class need has even lesser chance to drop for Your character of that class etc, just to make You buy more lootboxes. It is not too much to ask for to know what is in a product You buy and if a lottery/gamble what the odds (percent) are to get a certain win/pay-out/reward. Even professional gamblers are not stupid enough to not play the odds or to gamble on things where they don't know the odds/percentage. Only easily fooled amateurs do that. There is another controversy surrounding Bungie and Destny 2, where players discovered that the code was even made so that it said they recieved a certain % boost of in-game progression/xp that unlocks in-game ingrems (their version of lootboxes) with things like cosmetics while in reality they did not and had a lower % xp earned after they played a while. It was a scam basically and misleading information basically and Bungie had to apologize and remove that. That is what happens when some corporations gets away unregulated. Happily gamers are good at digging and doing math, spreadsheets and finding such things in the systems. This is not an isolated event that 3-4 players in LoTRO has made up.

Also link to one such petition. This one is specifically for UK Parliament only:

I added all that just so that You see this is not just the same 3-4 players in LoTRO that are concerned about all these issues. It's a global thing among gamers now.
Back to LoTRO. Then as Arnenna said. We don't know how many in-game will like or dislike things once they notice the changes, which they might not straight away until they start wondering why they get no more drops or why they can't open the chest in Mordor instances again. Or notice that some things have become bound and can't be sent to their partner, family member or friend.
It's amazing how many don't even read the forums or even the log-in screen. Just today before servers were going down I was in. As the broadcast messages showed up on screen people started going "what ???", "Whats this downtime for, patch, maintenance ???" etc. Not having a clue an update is coming even though it had been announced since friday (or was it saturday) on the log-in screen. Those people never read the log-in screen, even less the forums. Most of the friends I play various games with through the years never post on forums at all. Doesn't matter if it's GW2, STO, SWTOR, Civilization, RIFT or LoTRO. When they see things in-game they don't like, they eventually just stop playing and move on. I have tried to get some more involved, to voice their opinions but most won't. Just as they don't speak up irl but avoid conflicts and rather walk away. I have sat at restraurants with people being served food they said they didn't like and tasted bad. Still when waitress or waiter asks them if it tasted good, they say yes. It's alway easier to just float along than to stand up and state ones real opinion if that opinion is in contradiction with someone. It's considered being negative and a party poop if not just agreeing to everything and with everyone. Most people don't want to be percieved that way, so they just float along and they rather protest in silence by never going to back to that restaurant or stop playing that game. Which in my opinion is a shame, as then the restaurant or game devs can never know what people were not happy with and be given a chance to improve themselves. That is if they listen and want to.
