The frustrating bit to me is when they bought up Creature House Expression (A Vector art application) https://en.wikipedia.org/wiki/Creature_House_Expression rebadged it as a Microsoft product and then killed it. It was a really great vector tool in it's time. Buying up software companies and then killing the software is a problem we rarely talk about. AutoDesk has also done this with Softimage XSI, which, ironically Microsoft used to own as well.
