There is no one dictating that. The source code is still in the hands of developers, and your advice to me was to "open source it." All developers of 32 bit apps have that option, and they also have the option to maintain their source going forward.
Apple's decision to shed technical debt shouldn't be seen as them eschewing some moral responsibility to support old software.

I would consider it if I still had the source. But you should realise that saying "open source it" trivialises the amount of effort and emotion required to do so. Sharing your work with the world (especially if you are embarrassed by old code you have written) is not something that everyone finds easy to do. I would feel obligated to update the code, write build instructions and a readme file at the very least.
That would take a good few days of my time to make the code "presentable" before I would be willing to share it. I don't have the mental or emotional energy to devote to that task.
