Phonegap is a common JavaScript interface to native APIs. HTML is only tangentially related.

Building apps with JavaScript is doable, but has performance consequences that are severe on low-power mobile devices.

It's hard to fault Google for providing an open-source Java-compatible OS. It's not their fault if other OS builders are not compatible and actively block cross-platform solutions.

I haven't tried it, but I don't know a reason why one couldn't write an Android native app on Objective-C. You'd need a cross-compiler and technical/legal ability to port Cocoa though, the latter which I suspect would be quite challenging.
