There were three major themes that I personally saw:

1. "The onboarding sucks because I don't understand what most of this nonsense means." This comes down to, at least in my opinion, those with some sort of background in Bitcoin making stuff for those that most likely have some sort of background in Bitcoin.

2. "I see crypto bullshit so I'm noping the fuck out and not wasting my time." Saw that coming from lightyears away. A problem I've mentioned multiple times.

3.  "A lack of service-side moderation means this is going to turn into an illegal mess, if it hasn't already." This, to me, comes down to a mix of genuine concern plus political beliefs plus not understanding how to curate one's own content intake.
