Are you serious?
Linspire is a corporation, so it *could* be taken over, but it's got negligible market share and no interesting technology. No reason for anyone to consider buying it. Ditto Mandriva. Ubuntu is also a company but other than a rabid, loud-mouthed fan-boy base (with apparently no understanding of what actually makes Open Source Software really successful), they also have nothing interesting to offer from a technology perspective.
Slackware, Debian, Slackware, CentOS and the others you list as ripe for takeovers are not corporate entities. They are communities of hackers. How exactly would you think that someone would "take them over?"
Seriously, if you're going to write this crap, you should at least have part of a clue. You obviously know almost nothing about how Linux distributions work, and apparently no idea which ones are commercial and which are community.
