The argument seems to be that app developers aren't doing very well on the app store, and you're looking to the free and open web as the place where vast sums of money will be made? For the vast majority of these apps, I beg to differ. The web plays by the same rules as the app ecosystem: it's very expensive to monetize, unless of course you are creating value for someone who has money and minimal friction when payin…
I'll support this point: for so many services I'd be ok to trade off native performance for a smoother install process and independance from arbitrary rules. For instance amazon kindle app is severly limited by the app store rules while it has arguably no features that need to be native and does have almost no performance need (I wouldn't care if it took 250ms instead of 100ms to turn pages)
Same goes with apps like google keep or to do list apps. Whole categories of app would be better off as locally installed web apps, if only the OS had better support for them.
