You can complain that this isn't what a browser is for, but it won't really matter until you can distribute your favorite kind of software in a way that requires (nearly) zero effort and zero risk for your end users to get started with.
Open browser->type in appname->hit enter
Open appstore->type in appname->tap install (with what is likely to be less risk since it's not only sandboxed but also at least Apple's appstore is inspected)
If distribution is king, you're going to get more eyeballs from people browsing in an appstore than sitting out there at www.urlhere.com. Where you'd have to actively advertise in some fashion.
I stand by the viewpoint that all these issues that arise from misusing a tool. And the author isn't too far offbase either. As noted, a 10MB page is ridiculous and it sounds to me that should be in an appstore somewhere. That's just misuse of the platform and far off what was the intended purpose.
