While I'm sympathetic to bashing non-functional stuff, the JVM holds the record for languages. The CLR got the tail call thing partially right (AFAIK they didn't work well and weren't guaranteed) but due to the Windows only aspect MS chose, got almost no 3rd party language support.
The client side issue was much more to do with the terrible UI stuff and insistence on cross platform (hint: actual end users rarely care about cross platform since they tended to only run one platform at any time.) I believe MS was particularity enamored with Java but Sun slapped them away.
Client side was not lost due to lack of functional support. This should be trivially verifiable by the fact that fp is still only lightly used in industry.
