The perfect is the enemy of the good.
You're talking nonsense. The web is just the dominant way of accessing "app clouds" on today's internet. Users don't care whether the code running on their device is Java vs. Javascript if the end result is the same. All you're promoting with "put DRM in HTML" is for all the horrific things you dislike about native apps to be allowed to infect the web.
You're fighting the wrong battle. It's not "make sure the web wins over native apps" -- it's "make sure open wins over corporate oligarchy." DRM is the opposite of open. We should not allow DRM to be in HTML. We should not allow it to be in operating systems. We should not allow it to be anywhere -- content providers who claim they won't sell their content without DRM are just lying. Make their choice "no DRM or no distribution method" and they'll pick no DRM.
The Web is not a one way irrigation medium. It is about freedom. DRM is the opposite of that. Freedom is more important than money.
