In all seriousness though, the reason why services end up under DDoS attacks are wide and sometimes complex.
There is a likelihood that someone is simply upset at these services, or that there was a coordinated effort against source control programs more generally but its only succeeding against these two (that we're aware of), but not say, GitLab / GitHub.
Another example: they may be targeted simply due to traffic and volume, and this is an attempt to "dry run" DDoS techniques that may be used against bigger sites down the road too.
There's alot of room for why these things happen. I've learned that motivations and execution is very wide.
Of course the efficacy of attacking a service with lots of content is questionable, but the plan is to put on so much pressure that the service removes the content.
