It's specifically a macos issue. 32 bit softwares run naturally on 64 bit hardware on any platform, Windows, BSD, Linux, without any maintenance.

It's just an Apple trick to force financial turnover for owner of 32 software.

It's not that there softwares are not compatible anymore, it's MacOS which block artificially 32 bit software.

It's for the same reason MacOS block sidecar for device older than 2016,even if they are capable to run sidecar in the first place.

Your software doesn't run in isolation. It needs services of the operating system. Apple has to spend resources maintaining 32-bit software and consumers would rather they didn't do that.

Poor Apple, that's certainly too onerous of a burden to put on their shoulders.
