OTOH, there's the counter argument that if search engines and OS vendors are willing to pay for browsers, why should Facebook and/or Netflix spend any money? It seems to be the classic business case problem of, "well everyone else is paying for it already, and as a result we won't have much affect". I do, of course, realise that FB and Netflix very much have an interest in the web platform, and could undoubtedly influence it more if they were willing to contribute code. That said, it's probably worthwhile to point out to those who don't know that both FB and Netflix are W3C members, and have several people who contribute heavily to specs.
