If they make it difficult or impossible to acquire through purchase (false scarcity by removal fro market) or if despite purchasing a physical object, say a car, I can’t fully use it or repair it without special software I think an argument can be made for surfing the high seas.
More if it’s something that was available but only from one specific location several years ago and it’s no longer available or incredibly difficult to find for purchase. A good example would be certain old console video games that can be emulated now but have long since gone out of print and are either unavailable for purchase as digital or insanely expensive or unavailable for original hard copy.
There’s issues with “right to repair” too but that’s a different discussion, I think.
