Though unfortunately Subscriptions in software today are the norm, they are a malicious functionality. Any software that you already have installed should work whenever you want it to work. Having a timer implemented in it, so it will refuse to work, unless you pay every once in a while, is malicious.
This comment thread is for people to document various implementations of this malicious feature.
I definitely hate subscriptions...but they are certainly a valid choice for some products, like mobile data, or streaming services. But for software like password managers, or microsoft office (although i think they do provide a lifetime purchase), doing subcriptions exclusively is a rip off, especially if they are products that you don't use off and on.
