I estimate NF brings in somewhere just under 24 million USD per year from Aus/NZ currently. In my opinion that gives NF 24 million reasons to ignore grumbling from TV execs and distributors (who I might add are also getting a large cut of that pie). Bitching about T+S, IP and rights etc is one thing but so long as the pig is providing bacon, I can't see anyone willing to enforce T+S, IP or rights. Especially when their alternative income stream is negative.
Also worth pointing out that Sky probably have a very comfy position at present. By looking the other way while mostly geeks plug into NF- they don’t risk getting in an unwinnable war with NF by trying to shut them out.
