Here are some more to add to the list:

Running a proprietary anti-cheat at the kernel level that causes system instability and only works on Windows. Valorant and many others.

Releasing a sequel to a live service game that doesn’t port over the money / skins users have purchased in the original game over many years. Smite 2.

Paying publishers to make games exclusive to your crappy store on PC instead of making the store front better. Epic Games.

Making a single player only game with always on DRM and network requirements. A lot of games by EA, Ubisoft, and Bethesda.

That time Ubisoft tried to make NFTs in video games a thing.

EDIT: Removed Overwatch 2. It does allow skin transfers for ones the developer chose to keep in the sequel.
