I started rotating my BSSID weekly after I learned Apple and Google abused it to track the location of people and devices.
replyPermanent hardware or software IDs, such as the Windows GUID or machine-id on Linux (systemd) are inevitably abused for surveillance sooner or later.

You have all the good intentions, but since no one else does this around your location, I don't think you're achieving anything.

You mean, they used it so people trying to use their maps apps didn't have to wait several minutes for a cold GPS fix?

The same physical location showing a different SSID every week but the surrounding ones not changing would be deanonymizing you much more aggressively.
replyPeople mostly don't change SSIDs or even move networking hardware - e.g. AirBnBs.
Edit: and also are you still carrying a smart phone while doing this? The device which has GPS and a cloud internet connection?
For a while they had a paid program, I had a Windows Mobile app I could run with an external GPS dongle that would record wifi APs and location, upload to skyhook, who would occasionally cut me a check for my trouble. I made tens of dollars!
