on the one hand, I completely agree with the maintainers stance here:

I think there are whole fields that don't deserve to be treated seriously, and it's a good thing to discriminate against them, e.g. homeopathy and astrology. I would expect a medicine-oriented website to openly warn its readers that homeopathy is a made-up pseudoscience, even if the firm believers in homeopathy felt this is inflammatory, and people selling sugar pills were upset about their reputation being tarnished.

but I do not agree with disinformation. Modifying a package to state it's deprecated is slimy and underhanded. You've already put warnings up everywhere. You do not need to resort to tactics like this.

disinformation is what got the world into the shitty state it's in. if you spread disinformation you're no better than the cryptoscammers that do the same.
