Yeah, I only trust the random developers that are probably running windows to package my Linux software.
The people making those "stupid distros" are (most likely by number) volunteers working hard to give us an integrated experience, and they deserve better than to be called "stupid".
Yes but they are working in the wrong direction. Instead of trying to make ports for existing software they should just provide a standard environment for third-party apps.
How would you provide a "standard" environment when the third party apps all depend on other third party apps. What would the "standard" environment be for streamlink when it itself is part of the "standard" environment of streamlink-twitch-gui? How about curl, mpv, ffmpeg, libc? How do you evolve such a "standard" environment without the assistance of the third parties (because many of them will never help you).
Debian puts in a massive effort to be a long term stable "standard" system. I've found that effort to be wasteful. I'd much rather just take the occasional (although surprisingly rare) breakage than live with the limitations of old packages. That's a matter of taste though, and greatly depends on the effort of the upstream developers.
