Imagine if these countless of "Safari bad" sites didn't shill for Chrome by pretending that Chrome-only APIs are essential and standard web apis.
Reminds me of the days when all the corporate coders thought the IE apis were the only ones worth using.
So if you accessed $megacorp website on a non-IE browser it was your fault for not using IE and not their fault for failing interop.
(tbh I don't know if the list is simply Chrome-centric or if there's a good reason behind, but it struck me as interesting)
