I think something like

"Comment removed in protest of Reddit's API policy"

is best because if non-Redditors stumble across it it might dissuade them from joining Reddit. It is also very clear as to why you are unhappy.

I think it depends on what people make of it. Forums existed well before Reddit and Lemmy can scratch that itch. But so far a lot of the discussion has focused on Reddit and if real content doesn't replace it then Lemmy probably will fade away.

Also, devs can make a difference. If the experience gets better both on web amd mobile then it will help.

Have you tried Jerboa? I wouldn't mind seeing a couple of options out there, but I think I, as a developer, am probably going to work on improving Jerboa.

Magic, card tricks, and judo. I didnt participate much but I'd love to see what they would be like in the Fediverse

I've played with Mastadon a bit in the past but not much. I didn't know you could comment with that account. Interesting...

I'm glad I was able to help
