Quite interestingly, most files have a git timestamp from June 1995. Why is this?
It's odd; my first guess was Opera 1.0 release date, but that's in April. When it comes to arbitrary dates to use as the commit date, I have no idea why that was chosen. Maybe it'd make sense to someone with the actual VCS history!
There are only a handful of actual commits on the repo: two from 1995, and the rest from 4 days ago. It would seem that someone had a tarball of the source and specifically choose to backdate the commit, for whatever reason.
Opera Software ASA was founded on that day.
How do you know Opera will do that? I don't think they would care too much at this point.
If nothing else, they asked for an IP address in their DMCA.
They say in the takedown request that they want the uploaders IP and email to them down
