I think it's really interesting to see how many comments sorta make the assumption that the purpose of such an effort would be to ask grassroots activists to switch wholesale to Mastodon, install some specific toolset, switch to free software, whatever.
Nah, but I do think that if we tell people "you should be self hosting your website and email" we have a duty to also help provide that labor, just as we might volunteer to pass out flyers at a rally or set up the chairs at an event.
