You're not denying freedom to just those ~1000 companies, you're also denying freedoms from everyone they might "acquire". And if your definition of "acquisition" is 4 dudes with a source control repo and no market/sales, then you've denied a lot of freedom to a lot of people, not just some big corporates we all love to hate.

I personally know of probably a dozen cases of a small team of <10 people getting hired into various companies that all would be scrutinized under this reasoning, and yeah, I think that's totally insane.
