It only has 60 days and who is regularly browsing feature requests to up vote?
Can you link me what you're talking about? I'm searching for it and having trouble finding the thing you're describing. The only info I find is about their spam detection (which I already knew about but doesn't sound like it's the thing you're talking about.)
Simplex is good but they really need to rebrand their name.
Why not just use Signal?
I'm not aware of any code from Google it requires. What history of stealing data does signal have?
Can you explain a little more what you mean?
The only part that isn't open source is their spam filter.
It's not just aesthetics either. There's some rough edges in the structure of the UI too.
Friendica needs some serious work on its ui. One reason lemmy works is because there's lots of good third party apps.
Thermostatic voting
My guess is that ultimately it's to help deflect spam requests. Team is probably the ultimate decision makers but they need some way of defusing the onslaught of requests. I think dedicated user feedback platforms are usually better for that sort of thing but that's additional service maintenence and they probably want to use github as much as possible for everything.
