New Android phones have hardware-backed SafetyNet, new Windows devices have Trusted Boot (not to be confused with Secure Boot).
Both can and will be used to attest the browser environment. Linux devices will get hit (unless I guess we see locked down signed kernels, Chromebook-like things).
It's really slowly boiling frog situation playing out over the past 20 years. Since Aegis bootloader outlined how trusted computing will be created with predictions of allowing Internet access only to attested devices/people, we seem to be at the brink of somebody flipping the switch. Other predictions contained historic data/web changing as politically convenient with nobody being able to access/view the old original anymore due to only attested devices available.
