Some real numbers on this would be nice to have too. If you've seen any research in this area please share.

Do you have any sources for this? It doesn’t seem right to make a vague statement (a large chunk) which sounds bad, nor a somewhat less vague conjecture (maybe the majority?) without sources.
In my very limited experience, any developer who is significantly supporting OSS with code contributions is a high contributor for their employer, and if they don’t always do the agreed-upon number of hours/week for their employer, I doubt it’s far off. So I disagree with you anecdotally, which doesn’t matter much, and I question your sources, which matters more.
I am curious if there is actual data on the number of man-hours that are spent on open source per year, and how many of those are funded by corporations. My guess is that it is less than 1%.
