I also wouldn't feel safe using Samsung forks for work related stuff where security is very sensitive.

The product is perfectly fine as it is. The way I see it, if it's being advertised, it's being monetized behind the scenes. That changes incentives and usually makes the product experience worse. All it has to be is a window manager that supports standard desktop KB shortcuts (CTRL-C, ALT+Tab, etc.)

I also think a lot of people actually prefer having a separation of devices.
