Sorry, but this isn't true at all. Bitbucket works fine, and GitHub offers plans for non-profit groups for free: https://github.com/nonprofit

Self-hosting has multiple different options as well.

Registered non-profit <> non-commercial.

- a private website for my local sailing club. - a mod for a game - an open source project that requires a private repository for a few things - any project relating to a private community

None of these are registered non-profits.

Bitbucket is capped at 5 users as far as I can see, and self-hosting is just a recipe for lost data. I don't know of many amateur groups that can safely host a server.
