Google definitely should've researched this more, and they should probably change the name, but don't forget that this isn't as simple as just typing a new name into a text box. There's a mailing list, a compiler, repository and website names, environment variables, internal references in the code, a keyword in the programming language (which wouldn't have to change, I suppose), supporting programs other than the compiler (pretty printer, documenter, etc.), and I'm sure plenty of stuff I'm forgetting. Something as simple as a name change probably means weeks or work and almost certainly lost momentum.
