They always seem to have some critical limitation. Handbrake is too slow via flatpak to work. Flatpak Zoom had no camera access. Flatpak-only Zen browser can't use passkeys. Zen browser asks to be my default browser every time I open it, even though it is and I always say yes; is this a flatpak limitation? I don't know, and I'd prefer not to have to figure it out just for some theoretical benefits and more overhead.
A lot of hate for this, but it's true.
Incumbents aren't to blame for voters picking the familiar, that's a symptom of another problem.
We're seeing what an inexperienced government looks like now. They don't know the limitations they're supposed to have, and they don't care.
