If you bought photoshop back when it was not subscription and Adobe did not inform you that your license had an expiration date you can in fact do whatever the duck you want to it because you purchased it, you did not rent it, you did not subscribe. You purchased it and it is yours for life.

Matter of fact you have no idea if what you are suggesting would fly in court because I am pretty sure you don’t know about any previous case like this that has been even tried in court.
