The last year of the anime is the one exception because it has heavily (and I mean heavily) relied on nostalgia and hype building as a source of its quality. Aim to be a Pokemon Master is in the style of the "old" Pokemon anime (If you don't know, the companions for this series are Brock and Misty, and Ash uses a very diverse distribution of his Pokemon). I played SwSh for around 4 months and then it sunk into that cycle of "Bank/Home/whatever gets unlocked and all of the "super fans" go rabid and it's not fun anymore" that has been happening for the past decade. PLA was a direction that I was not at all interested in, and Gen 9 furthered that direction. TPCI's current product lineup and their desire to create and push outright dystopian spyware like Pokemon Sleep just further pushes me away.
2020 was a huge year for Pokemon for me because of all of the old beta / source code leaks that happened. It made me realize what I liked about old Pokemon and new Pokemon does not have it. And then with respect to Game Freak, with Masuda close to retirement and Ohmori being the series lead mixed with games journalism wanting things I want (see the post I just made about JRPG and FFXVI) I just don't see the point anymore. There's no reason to waste cycles thinking about something that I'm not the target for anymore. I also don't support the existence of "Expansion Passes" in JRPGs full stop.
Again, I'm not saying you're wrong to lose interest. Just that it's weird to formally "quit" instead of just not bothering with whatever new stuff comes out. It makes a bigger deal out of it than it is.
