I see what you're hinting at but the point of that question is lost on me.

That's like going up to Elon Musk and asking, why make electric cars when most people drive internal combustion engines?

The point is that it's not entirely useful for employers, which seems to be what you're concerned about. If 80% of people are committing to private corporate source control, and 20% are committing to private github accounts, it's not readily apparent why you would care to see some vague statistics about commit frequency for 20% of your candidates.
