I do, but the outages have not imapacted me since I keep a local backup (I also haven't needed to do any deploys during the brief outages).

I could host git repos cheaper than github with a $20 slice over ssh. So yes I pay extra to github for the additional features.

Edit: I also enjoyed reading about Github's custom stuff (like bert/ernie)... clever stuff that most teams would determine wasn't worth the effort, but that has worked very well for github.
