F# comes from Microsoft Research and was notoriously ignored by the corporate side for years (and still is to some extent). So I'm not sure F# has really ever been a project of Microsoft corporate interest, and now there is the F# Foundation which has many non-MSFT people and companies involved.

While I like Erlang a lot, I'd say that Ericsson still has quite a bit of corporate control and interest. It's not always a bad thing to have companies involved in the success and advancement of technology.
