The company I work for creates STB software, and while we do use a large number of open source components the message from above is to avoid GPL where possible. Any use of GPLv2 must be signed off after review, GPLv3 is simply banned.

Unfortunately most companies in the sector, from hardware manufacturers to integrators, have equivalent, if not worse open-source policies. They are willing to take the hard work of others where it will accelerate development, but view sharing back as a loss of control and competitive advantage.

This is in part due to pressure from operators and content providers, who are very fearful of losing control over distribution and tend to view anything open with deep suspicion.
