To be fair, developers haven't moved this way because they're dumb. The web has just turned out to be a _remarkably_ accessible and efficient distribution platform, and that currently trumps the cost of actually running the software. After all, it's what people are able to do with the software that matters. But it also means there's some relatively low-hanging fruit these days if you find a niche where performance is much more important than accessibility :)
