No that's a mischaracterization.
I'm saying I think it is important for free and open systems to be competitive with closed ecosystems, and to take advantage of the power of local systems.
I believe in a world where we - as developers - can build systems that have both maximum safety and maximum utility for users.
Currently there are two ways of distributing software that takes full advantage of the hardware users have:
1. AppStores, with centralized, permission based certification of developers in an attempt to make apps safe.
2. Binary downloads, relying on the operating system to make them safe for users.
I believe there should be a third way - a platform that sandboxes users from the worse things that are possible and breaks reliance on cloud platforms.
I think the web platform is the closest to achieving this. I think the security and privacy concerns are valid and well-founded, but I think the trade-offs in pushing permission-based systems are worthwhile.
Take this project as an example. The alternative to web-serial is to download a random executable binary and firmware written by who knows to your computer, with full read/write permissions. I think that is a riskier outcome for users than enabling this API.
