Apple has been warning the Apple community for a couple of years now about 32-bit support going the way of 16-bit support, so this shouldn't have been a surprise to anyone. Apple has ALWAYS been like this, it isn't something that Timmy cooked up.

I would suggest that you plan a transition away from Apple. If you need any help, let us know. In my case, it was a great 20 years, but It Just Works means Windows 10, not OSX.
