The only way for the "open" web to evolve is for Google, Apple and Microsoft to agree on a feature, spec it out and roll it out to their different platforms. All anyone else can do is twiddle their thumbs hoping they don't fuck it up.
We sandboxed away innovation, so now all we have is web apps that process text, video and audio all in the same way.
For the point of the developer, maybe. From the point of the user, not really; at least for many of them I can disable updates and keep running them even if the company goes bankrupt. The ones that depend on cloud services are arguably the worst of both worlds, though.
1) Some would say that the open web isn't so open anymore, and is under constant assault. One example might be the recent W3C adoption and endorsement of EME.
2) The fact that the open web "lost" in the battle for mobile dominance is a thing. Most "serious" apps have a native version on at least iOS and Android, and the webapp version (if there even is one) is usually a worse experience.
I would like to think the open web has not lost yet, and that progressive web apps still have a great chance of taking over. Nobody wants to develop apps for at least three platforms. Nobody wants half their user base use old versions. Nobody wants to fear being dropped from some walled garden without any recourse.
There are still good technical reasons for some native apps, but that will dwindle more and more.
