One thing internet activists don't tell you about people hosting their own websites is that that website is still linked to a single point of failure: the person who owns it. For example, I've seen various #YouTube mirror sites just... die without prior notice and vanish without a trace. Like, several of these.
A more recent example seems to be frutigeraeroarchive.org since every device I've tried to connect to it on gives a connection timeout. Oh, there goes a bunch of important history, media, and resources on #FrutigerAero because the single person manning the site just... vanished or forgot/couldn't pay the hosting fee. Fun! Just because a site isn't run by a company doesn't mean its safe or won't vanish without warning.
