For web & phones, I'm inclined to agree; a native app outperforms a web or hybrid app any day of the week. I do believe Facebook and Google are companies who ran into limitations though, binary size, number of classes / identifiers, build times, for which using web technology was a solution.

But for TVs, ehh. There's a lot more fragmentation on the TV market. And if things were slightly different, we'd have a lot more fragmentation on the mobile market as well. Actually there are plenty of mobile alternatives, but developers don't really want to support all operating systems - and these cross-platform tools often have substandard support for mobile operating systems that aren't iOS or Android.
