I used to use Ubuntu in the past, and it wasn’t Unity, Upstart, Bazaar, Mir, Launchpad, Snap, Amazon ads integration etc. that convinced me to look elsewhere, it was that I found out how other, not commercial distributions, integrated and instrumented its user base into their development.
Instead of having to sign a CLAs when contributing and signing your right away to some corporation, you become part of the community. (Update: It seems they have switched from their Copyright assignment, so something not as invasive in 2011, which is good. But they still require you to sign a CLA.)
So always look who is developing the distribution first, are they individuals or is it one company. And don’t let yourself be bated into the dependency of one company, because then you will be the victim of enshittyfication eventually.
