Yes, that is "fucked" up. The same way it is fucked up that not all VHS you once bought and own have been preserved without loss and none of them will forever. The same way it is fucked up that a software product you once bought and own won't be updated to be usable with your requirements forever.
The mortality of a product does suck, but a) this isn't exclusive to the greed of subscription services and b) you don't need to use a product til the end of time to make it worth it. E.g. I don't use Netflix anymore, but everything I was able to consume during my subscription was ridiculously worth it to me.
Let's say you paid $150 for microsoft office. One day microsoft says, we are only doing office 365 subscriptions and when you launch word, it will not let you use it. It makes you pay for a cloud subscription instead.
