The aged-out activation servers are tired and ill-performing after 15 years of continuous service. Nothing that old lasts forever.
Besides, CS5 was built for WinXP, not Win11. Even if you could activate it, there's no guarantee that CS5 would perform as expected on the latest operating systems. Too much has changed since 2010.
You've gotten many years of use from a product that had a shelf-life of 3-5 years. That's nothing to complain about.
