I felt that way too, but having used it a few devices as an end user I enjoy being able to close the browser and have the whole stack disappear. Instead of having to install a creepy Logitech tool to pair a mouse with a receiver, as soon as that task is done, goodbye Logitech. I guess a real concern is manufacturers stop offering native drivers, but for the majority of hardware the PnP or the Linux kernel just handle it.

There's a real risk of losing the ability to control your device if the manufacturer stops hosting their propertiary WebUSB app, too.

Standard USB drivers aren't going to disappear from my disk and can be reverse engineered long after its manufacturer has dropped support or gone under.

My mouse uses a WebUSB app to configure stuff. I just downloaded all the files that it uses, and now I can use it offline.

Nothing really stops you from reverse-engineering a WebUSB app either.

The question is if users will consistently have the foresight to archive such web apps, especially if the manufacturer has set up their bots.txt such that The Internet Archive skips it.

Traditional programs are incedentally archived by nature of having to be downloaded. They sit in downloads folders, old backups, thumb drives, etc.

So what is an example use case where you'd prefer to do X without using this particular tech?
