The ad bombardment will be the end of non-free software.
IIRC the Ubuntu change was pushed in a non-LTS distribution.
As an aside I think 5 year LTS is too few, with the advances made in AI/ML in the last decade five years on os support means that 80% of all the tooling is broken now, at least without spending lots of time backporting or hacking fixes in.
Ubuntu LTS releases are 2 years apart. You don't have to keep using 5-year old LTSes, do you?
