It is still your choice
You can choose to stick with tried and true yet out of date applications that force you to remain on an older operating system.
I can sympathize with your predicament.
But you still have a choice.
You could choose to replace legacy applications if you thought they would be better for business.
You could choose browser-based applications over fat clients which would work across many OS platforms.
You could choose to run legacy applications on a virtual machine.
