It's always been very clear in their Terms of Service (which obviously everyone reads carefully...):

The third bullet point at https://docs.github.com/en/site-policy/github-terms/github-t... --

> One person or legal entity may maintain no more than one free Account (if you choose to control a machine account as well, that's fine, but it can only be used for running a machine).

This is the primary reason why I have only ever used my own personal account for work stored at GitHub. If a company is expecting its employees to use a separate work GH account, one assumes that company is planning to pay for all those accounts for its employees.

Having said that, given that many people do use separate GitHub accounts for their separate private and work personas, and many organisations seemingly expect their employees to do so, perhaps GitHub could consider revising this Terms of Service restriction to better reflect reality.

There have also been times when I would like to have access to a second GitHub account for testing purposes. (In particular, for testing GH behaviour when the accounts corresponding to PR commits, PR creator, and PR merger all differ -- see for example <https://github.com/isaacs/github/issues/1368>.)

I maintain two but my personal account is a Pro account.

I imagine some large number of folks that have two accounts are Pro on at at least one of them, if not both.
