If you interpret their sub rule "Posts must be relevant to the open source ideology" in the strictest sense then I guess anything about FUTO is against their rules, since it isn't open source.
Still seems a bit dickish to delete comments like that. ¯\_(ツ)_/¯
You don't really give enough detail to give specific advice. All I can say is I left it too late to reconnect with mine and it's one of my biggest regrets.
The only half reasonable argument I've seen is that requiring pasteurisation (supposedly) makes it difficult for small dairy farms that want to sell direct to consumer, and forces them to sell to large milk companies for a far lower price. I have no idea how valid that argument is.
