I would probably really enjoy working for a company like Mozilla where the motive/mission is Generally Good. I'm not easily motivated to go build some silly App or Website to make money for Investors....
But seeing that they're willing to just ditch a bunch of employees scares me away quite effectively. I'd have expected the company to have hired bright, talented employees who could be repurposed and moved to other teams.
I guess even if you're off doing Good Stuff that isn't really a guarantee that you will be treated as a long term investment rather than a gap plugger.
