Microsoft would take a severe hit both from a PR perspective, as well
as incurring significant legal risks if they did that in certain
jourisdictions --- in particular, I suspect in Europe, if Microsoft
were to break the ability of Linux distributions from booting, it
would be significantly frowned upon.

So Microsoft may have privately threatened this to certain Red Hat
attendees (threats are cheap, but it's not obvious that they would
necessarily follow through on this threat.
