Get a grip.
Point is its a game, its free and its optional. If its affecting to the point that you post sweary rants and you can't simply not play then you have a problem that is not healthy for you.
Also nonsense to say people are scared to speak up, in fact why would anyone be scared? Thats just ludicrous on so many levels.
Also regarding revenue you haven't a clue how this works- the "decline" is just app store based figures (publically available data even states it as "in-app purchase revenue"). The "decline" you mention begun in 2022 when the webstore opened- this isn't a coincidence. Yes, they've never hit the 2017 record but clear that since then the only real drop off was due to the webstore opening.
A lot of payments now go through the PC app or webstore now so Apple and Google don't get a cut and prices for players are "slightly" cheaper not to mention players getting rewards if they pay through the store. Therefore if you spend money in the game you'd be mad not to use the webstore wherever possible.
Even by app store only figures the game makes around $88m a year, and you can bet webstore sales added mean its far from in decline.
