"Apps running in those compatibility layers are much less contained with less isolation from the Linux kernel, not more."

Being isolated a little bit more from the kernal offers an illusion of privacy meanwhile where you are, what you have installed, your photos and friends are available to other apps at a much higher level. I understand being able to slow down a nation state actor is important but most privacy concerns for average people happen at the OS level not the kernel.

This claim is false. Isolation and protection from the kernel is vital and it is already targeted for exploitation, and will be targeted even more as time goes on. Properly updating the kernel and improving its isolation and security is the bare minimum for even below average users, not just for high threat models. The claims you are making are unsubstantiated.
