They are also, by complaining, incentivizing other people to not even offer free services in the future. Why set yourself up for accusations that you're 'breaking your social contract' or whatnot?
"Responsibility" is a word mostly thrown about by people making demands as if they are somehow entitled to full service contracts on stuff they got for free - which is especially fun when said provider offers actual service contracts.

Packages are deprecated and orphaned all the time, including in OSS package repos. It's often silent by virtue of the package maintainer just... ignoring it, until someone takes administrative action by just whacking the package.

I don't really see that as having any impact. I also don't see a packing method for an active free project being deprecated as anything having "disappeared". People just need to update their deployment, just like if the release had included a breaking change.
