Interesting points you bring up. A point to consider is that many companies, even surprisingly many of the Fortune 500s, have very dedicated IT teams to support a web infrastructure, and so choose to make their applications using web frameworks to emulate native. I give you that it's not ideal, but when looking at the bigger picture, it just makes sense to use web rather than to force them to spend months getting ready for native support; so there might be a place for each use case.
