This is so silly. First, Apple’s history is that they will continue to support older hardware with security updates even if they can’t support them with the latest OS.

Sometimes older hardware isn’t capable of supporting new features. In prior cases it might not have a 64 bit processor or not enough memory, and of course you can’t expect support in those cases.

In this it’s old WiFi hardware that can’t support new features. It would be dumb for Apple to take engineers off making Big Sur more solid for 98% of Macs to waste time on this problem for a tiny percent of the active base.

Apple is doing exactly the right thing. Make it work well for the vast majority, then see if they can take it farther back in the first couple of bug fix releases.
