In the past we have had few "code repos" from Savannah to Sf and few sites like freshmeat to spread the news, the code, the idea. Of course we also have had and have used usenet.

IMVHO today it's time to evalutare ZeroNet for project sites/blog and something like IPFS (not much convinced by this project but...) for code and repos to AVOID depend on someone else server's switching to relay only on us all.

For me there is no difference in GitHub or GitLab or Bitbucket etc, nor between Google and Microsoft. In an era of diversity companies are not a problem, in an oligopolistic era like today, in an era of proprietary platforms instead of open standard companies are a problem and should be avoided, especially if they are big, especially if they push mix of proprietary and FOSS solution.
