I don't really think it's fair to get mad at someone for prioritizing meeting their own needs. It is however entirely fair to be furious about societal structures that place increased financial value on industrialization and privatization over community cohesion.
Your teeth are bared in the wrong direction. We do in fact have a common enemy here.
I find the criticisms of the founder pretty seriously overblown. My interactions with him have always been positive. He's on the spectrum and a lot of people engaged in pretty serious abuse toward him and the project he created... so I'll give him some slack.
I've used GrapheneOS for 5 years. It's good, the project has integrity, and there really isn't anything that meaningfully compares in meeting its goals. It's proactive in that they actually do meaningful security research and implement solutions. People who troll on the project are either straight up bad actors or just stupid.
