Hard as in writing code in three different languages. Apart from that I think tech community giving too much credit for Apple and especially Google. They could have fixed this native vs html5-js-css thing two versions ago.

Three different languages that provide vastly superior runtime libraries and tooling that facilitate implementing first-class applications on the target platform.

I agree that supporting multiple platforms is suboptimal, but instead choosing a suboptimal common platform isn't any better.

We already tried that once with Java desktop applications, and Java at least tried to provide a viable common widget/platform toolkit.

No, we tried it once with web applications, and it worked brilliantly.
