GitHub became more a social platform rather than just a code repository and it let you build up a community - I can't argue with that. But it's a large commercial company that doesn't really care about you. Now, when it's microsoft, more so than ever. I'd never trust my data to a company like that. Last time I trusted Google I lost all (decade worth of) email. I worked in a company that WOULD sometimes make devs manually scrap user data from the database when it was our fault or users were somewhat important, but that's more like exception to the rule.
