No reason to be ashamed, I have seen many companies that only use platform SDKs (e.g. aC++ on HP-UX) and IT has the last word over what tools are allowed on dev machines.
However the situation is no different in other languages.
I am aware of some companies still using Java 5 on production, just to cite one example.
I know one major retailer whose terminals are all a DOS variant whose sales ended in 1999 and whose inventory is hard-tied to SCO UNIX. Got future-proof written all over those. ;)
Note: Many key operations, including the backend, are on AS/400 and mainframe. Much wiser choices. Needless to say, the employees tell me that part never goes down.
