There's a huge shitstorm about microsoft aquiring github. On one hand there's a company that's been one of the technical leaders since the beginning of home computers that got famous while hiding it's code, on the other hand there's a platform that hosts open source projects. That's what brings many to an inner struggle.
The trend of the most open source heads goes to migrating their GitHub repos to GitLab. You can see that on GitLab's import statistics using the implemented GitHub API.
As I didn't make much use of github up to now.. At least I created a gitlab account. I don't know what will change for github in the next months but reddit's programmerhumor subreddit atm maybe gives a little hint.
