It is an _example_.

OTOH do not forget that Arch is a family of distros now, not a single distro, just as Debian is.

In fact I suspect that it is the 2nd biggest family of distros, after Debian.

Debian encompasses many dozens: Ubuntu, plus dozens of Ubuntu derivatives including Mint, Elementary, PopOS, ZorinOS, Linux Lite etc.; LMDE; Devuan; MX Linux; SpiralLinux; etc. etc.

Arch now encompasses at least Manjaro, EndeavourOS, Garuda and more. https://wiki.archlinux.org/title/Arch-based_distributions

But that is not the point.

The point is that _tens of millions_ are running non-Debian-derived distros, mostly ChromeOS and CloudReady/ChromeOS Flex.

Offering a .deb package is _not_ a useful approach to offering a generic Linux package, no.

The RHEL and SuSE family is definitely bigger than arch and arch adjacent distros but I agree with your point

Yes, that's true.

FWIW, I have tried both the Snap and AppImage versions of TB 102.

Both were very easy to install. The problem is that Snap confinement meant that TB could not see my existing profile. I just got the first-run wizard.

This did not affect the AppImage, which is working well.
