Yes, they are allowed for software. But not for e-books--which are the subject of this conversation--or for other copyrighted works.
And-also-yes, the copyright scam is pretty much over. The marginal cost of another copy is zero, “for a limited time” means “forever minus a day”, and our culture is being stolen from us via inability to preserve it, use it later if we did acquire it “legitimately” but someone no longer feels like running their “permission to have that” servers later, and by being dynamically retconned such that “bad things” are dynamically edited out and, if you remember that they existed, you’re wrong (and getting gaslit over it).
It was basically a “social contract” that, while not everyone agreed with, they mostly admitted “existed”. Not so much now.
Regardless, people should be aware of what the law is. It’s a different choice to decide to violate the law and take one’s chances than it is to rest comfortably knowing that something is entirely within their rights.
