Pushing a shitty launcher,
Fuck them. That's horrible.
selling abandoned games,
Why is this a problem? It's literally a good that those games aren't being lost to oblivion
selling incomplete games,
As in unfinished? That's the devs' fault.
putting DRMs on multiplayer,
Without that there will be a humongous rise in cheating in online games
selling a lot of low quality games
Literally not an issue. They are a marketplace and frequented by indie devs, they can sell as many shitty games as they like. In fact I would like them to be more of a platform like itch.io
not expanding their overworked team despite the profits they make
You have no idea what you're talking about, their org structure and project setup is not public and there is no way to know how "overworked" any team is as an outsider. You don't even know what teams they have.
