if we want to play tinfoil hat hypotheticals.. lets go

if government gained access to github and compromised it. yes people will just use a different software development site to distribute open code from. however people would lose trust of the new source. and it would take time to build up reputation to trust the dev team and the code they have moved to the new development site.

yes the code is open and anyone can review it. but currently people just review the changes that are added to github per release, and dont actually re-read every single line of code per each release. however changing to a new development tool site, means people would initially need to review the entire sourcecode just to be sure its the same as the old sites version. .. so it would take time to trust a new release candidate from a different development tool site
