Such naming is part of my break-up plan for the tech giants. If you break Facebook up into three successor companies with competing networks, you run into the problem of what do with the Facebook brand. It would be unfair and counterproductive to give one the brand and have the other two create new ones, so my idea is to give them color versions (e.g. Facebook Red, Facebook Green, Facebook Purple). Eventually they'd probably rebrand, but it's the best solution I can think of to start.
