Their outside communication is nonexistent at best

Eh, they’re decently active on Reddit, I guess. They send the occasional newsletter regarding new features if you don’t unsubscribe (and they’re pretty good at not spamming with those, imo).

development speed is unbearably slow

I see people say this all the time, and while feature updates are kind of slow, I’m also not lacking anything, personally. I would appreciate it if they smoothed-out SimpleLogin’s extension, though. That thing is weirdly clunky to use.

Agree on the Linux bit, though. I’m surprised they haven’t put more work into that.

Overall, I’ve been a happy customer for a few years, personally.
