It seems like the point is that Microsoft would be developing some sort of alternative to the kernel with similar functionality for antivirus providers, that doesn’t need to have kernel level access. Anticheat uses a lot of the same techniques as kernel level antivirus to detect malware, thus it would probably have to adapt to this new system.
I think the article is more commenting on how Microsoft is directly partnering with antivirus companies for this new system right now, while they’re not directly partnering with anticheat companies, even though they’d probably have to migrate to this new system regardless.
Yes.
Even if it didn’t explicitly stop my biometric data from being taken and transferred to a government database every single time I fly, it would be a vote against the system itself existing. The whole reason they are allowing people to opt out right now is to test how acceptable it is to people, to hopefully make it mandatory given too little pushback from the public.
Opting out doesn’t just protect your biometric data now, it protects everyone in the future from having their biometric data taken from them without a choice if this system is allowed to spread unopposed.
