What Frenk is effectively saying is that he doesn't want his packages redistributed by distros. Since this is a dependency of home assistant, this means home assistant (as the whole package) can't be distributed if his wishes are respected.
Additionally Frenk didn't react to any proposal to still distribute home assistant and it's dependencies while respecting his wishes. This seems like a pretty clear-cut case of involving the upstream community, to make sure they're aware and ok with their dependencies trying to block distribution or to change something if that's not the case.
The whole saga left me rethinking my home assistant usage, since it seems like this could become a larger issue with other distribution mechanism not sanctioned by upstream.
