Do you pay for GitHub Pro?

Yes. GitHub used to (still has?) a one free account per person limit. I like to keep my personal account and my work account separate, especially with different SSH keys and access tokens, so I pay for a Pro account.

The idea that some weekend, hobby, side project uses the same GitHub credentials as my day job is enough for me to justify the cost. I probably could use two free accounts on the sly, but for a service I use professionally (freelance contractor) it's easy to justify and not worth the ban (however unlikely).

My usage doesn't exceed the free tier on either account, so I could combine to a free account if I wanted.
