Don’t know why they’d put “Developer of the Newpipe app” as dev though

My guess is that they did not want to take credit as the developer of NewPipe itself. As if to say “We did not develop NewPipe, we just packaged it as a Flatpak”. There is probably a better way to get that across in the byline, but I believe that is the intent.

Not sure I would call that “active”. No activity in over a year. And even that was just changing a couple markdown files.
