Stopped playing from a burnout that came from a similar reason actually. There was always a big variance in how good farming methods were but with berries giving people such a source of money everyone could experiment with new bred mons pretty heavily a couple times a week without having to farm forever.
There's still profitable farming methods but they are all very time consuming or require outright cheating like multiple devices/alts playing gyms at once during the battle animations, things like walking on single sleeping meowths to catch them when they have items, life orbs, berry pickup while also hoping for snorlaxes, geodudes. All of this was fine and actually kind of fun in the past because you could do the one you liked it as a bonus to get extra money, but given the nerfs to every single of the methods you're basically just told to play market flipping or play on multiple devices at once, which is ridiculous.
Also the new abilities that could've freshened up some farms like vital spirit and hustle still don't work, despite them being reported on day 1. Cute charm is nice but it doesn't really change much at all on its own, seeing how the one really good thing it worked for (snorlaxes) was nerfed less than 24h after introduced.
