It is. I felt like the Bsky team was too focused on protocol in the beginning, and they missed MANY opportunities for user growth.
I recall a comment here that said ~"you guys missed the chance of a generation by staying invite only." I had agreed with that at them time. However, X/Twitter keeps making decisions which make the small, underfunded, yet smartest team in the land look pretty darn cool. (they were cool af the whole time)
I highly recommend listening to an interview with the CEO, Jay Graber. I became a huge fan of her vision after doing so.

I wouldn't call it "absolutely fine" by any means. It's way too slow to render for me to use (took about 30 seconds to render the submitted link on my phone, mastodon took about 10 seconds to render a toot). I'm beyond sick of slow web pages.
As for performance on my iPhone 15, on a 5G (not 5GUW) network, it loads in a second and a half; I just checked. I have some complaints with what RN does in terms of affordances but performance isn't a problem.
