Absolutely - people now ask to see your Github repo as an integral part of your CV without even really considering if you might use another service.

And you don't exactly want to pitch to them how you don't have your code on Github because you use this other "fringe" service which even if they look at it they are going to find unfamiliar.

I now host 50/50 on Gitlab / Github because I'm not really affected by this, but I'm conscious of it.
