Is Microsoft/Apple/Google/etc. prepared to pay me for software that I've previously purchased but is incompatible with their newer OS? Plus any costs associated with finding new software, training on the new software, migrating to the new software, etc.?

It's the application developer's responsibility to maintain compatibility. That's why Windows offers people dev preview builds.

The people who make the software you use don't do that? Don't use their software.
