I think your feelings are perfectly valid and you should listen to yourself, but also realize that you'd do best in not generalizing it to be anything but personal.
...And from someone who was deep into Ethereum tech starting 2014-2015, I recently got surprisingly really hooked again on Bitcoin. Lightning is fun and addictive, and it feels like we're close to some kind of watershed there.
Hopefully you'll find something new to be excited about soon (or take a break from it all, sometimes that's what we need as well).

The reason I'm fed up with Ethereum right now is mostly the "defi" hype where it's mostly anything but decentralized in any way if you look just a bit closer. This goes for pretty much all the projects with significant traction today. So many corners are cut just to be able to ride the wave of the hype train. "The admin with full control is only until we are out of beta, for safety", "The centralized coordinator on AWS will be replaced with a gossip protocol by V2", "The owner multisig will be replaced by a DAO", "the project leads will do all the coordination for now" and other BS rationalizations all completely antithetical to the ideology.
One major strength of Ethereum for many years have been the community. Recently I feel like greed has taken over.
