Beyond that, even if git *did* somehow provide strong authentication of 
the configured email address for commits, it's open source software so 
people could still quite easily disable that authentication to spoof 
commits as other people. They could also use some other software 
(possibly that they write themselves) that manipulates a repository 
without doing that authentication.

While the data is entirely on an untrusted system (however you want to 
define trusted), the operator of that system will always be able to 
manipulate that data.

The alternative to this would be to require all commits to be 
cryptographically signed. But, most projects consider that to be too 
much of a burden. After all that only covers who made the changes, while 
for many things the content of the changes is much more important.
