I once heard Joshua Schachter describe this kind of acquisition by a public company as "somebody in corp-dev falls in love with your product and has to have it."
In other words, it's not repeatable. This is nothing new. It happens all the time.
Quite so. In the real world, things don't always have to make sense for them to happen. That counts for both good as well as bad luck.
Counting on luck, of course, is not a reliable business plan. Whether these folks deserved all the money they got or not is really a moot point - your best shot at success remains to put yourself in a position where you deserve it. You may still not achieve it, or you may grossly overachieve it, but still the best way to go overall.
