"Wave" might be too strong a word, but I've seen three or four posts on HN in the last few days that were pretty critical of Github's closed source nature and insufficient transparency.
I'm not sure why offering a free software edition somehow gives you a pass. Both Github and Gitlab are commercial entities as far as I know.
Anyway, my concern wasn't a big deal, I was just a bit taken aback at the opportunism. In retrospect, I think my reaction was a bit overblown.
