The M2-series and M3-series of processors seem to use the same ARMv8.6-A extension, however nested virtualization is restricted to the M3-series chips. Is there an architectural reason why this is?

I'm running Xcode 14.3.1 (macOS 13.4.1). When I go to use Content View an error message saying 'promotedcontentd quit unexpectedly' spams my screen. Pressing "Ignore" or "Report" just causes the message to reappear a short time later. Digging around in my DNS-level content blocker shows iadsdk.apple.com being blocked, with the error message appearing shortly after a request gets blocked. Why is this? What does this domain do?
