The Samsung browser is a Chromium wrapper. Some people dismiss wrappers around Safari on iOS, although I think there are more important things to worry about than exactly which rendering engine gets used.
How about letting users decide to which capabilities they give permission depending on what they need? I don't want to push them to download and install a whole software package locally which has usually access to more data and hardware APIs compared to a webapp that temporarily lives in a browser tab.
No. In a war between Users and Developers the users always lose if there is monetary gain to be had.
It isn’t as simple as “hey if you don’t want this permission that’s okay go on ahead !” It’s “we’re going to get this data whether you like it or not”
I rather Strong strict privacy laws before opening the chrome dominance that will come.
