That only applies to unstable distros. Stable distros, like debian, maintain their own versions of packages.
Debian in particular, only includes security patches and changes in their packages - no new features at all.* This means risk of breakage and incompatibilitu is very low, basically nil.
*exceot for certain packages which aren't viable to maintain, like Firefox or other browsers.
What stops companies from having a shell corporation use the code, and then that shell company rents "services" at a very low cost to a large corp?
I'm thinking something of the opposite if what Google does, where Alphabet (""located"" in Ireland) rents the Google logo to Google, allowing Google to say that their revenue is much less than it actually is.
EDIT: After some research, it seems that they stopped doing that: https://www.theguardian.com/technology/2020/jan/01/google-says-it-will-no-longer-use-double-irish-dutch-sandwich-tax-loophole
But a similar scheme being applied to this license does concern me.
