> There is nothing that makes an installed app, with higher permissions, more trustworthy than a web app.
Yes, there is. The fact the user has installed it.
> Getting rid of js altogether is just throwing away the web to make it something poorly performing and requires sending all data back to the server - so not really a serious option.
Not the web, just webapps. The web will perform better afterwards.
> Browsers only exist to allow interaction with websites, and as such they should follow specs and allow them to be used.
Yes, but those specs have to be sane. Which means even a completely untrusted party – that's what a random website is – cannot abuse them.
> Websites are more important than browsers by definition.
Nonsense, either is useless without the other. Websites are content, browsers define how they're viewed.
