Yeah, our laws still really haven’t caught up to the realities of today. Our copyright laws mostly predate the current era of our IP-dependent economy, were ghostwritten (or straight-up written) by the industries they were supposed to regulate, and then passed by lawyers a few generations too old to even know what they were regulating (if they bothered to read the bills at all, or even used the products). That wasn’t so much an example of “all commercial software is evil”, just of regulatory capture and a government that long ago failed its everyday constituents in favor of its elites.
Meanwhile, if you put aside the legal semantics, there ARE substantial and meaningful differences in the way different software is sold: Not just Steam vs GoG, but also Path of Exile in Asia (pay to win) vs the West (cosmetic lootboxes), Adobe vs itself a few years earlier, Microsoft vs itself every few years, Jetbrains vs Oracle, Redhat before and after IBM, games publishers before and after acquisitions and mergers… all of those make noticeable differences in the way a consumer is able to pay for and keep a product, or not, even if they’re all just strictly “software licenses”.
We may not yet have clear enough legal verbiage to differentiate between “owner” and “'licensee” when it applies to digital products (at least not to the common person), but despite that, there ARE real and meaningful differences in the actual real-world way software is sold or rented. Companies don’t HAVE to be assholes towards their consumers. Many just choose to be because they CAN.
But even back then, it varied widely between companies. One company might check for a physical hardware dongle connected to the printer port. Another might just have you type in a code from the back of the instruction manual. And yet another would give you 1/3 of the game as free shareware, and if you paid for the rest, they’d just send you the floppies without any DRM. On the other extreme, there was also those self-destructing DVDs that disintegrate after a few plays.
Books, music, movies, games… they’ve all been subject to unauthorized distribution and piracy for as long as they’ve been around, and for sure that has a toll on their profits, but despite that there have always been less evil and more evil companies. It’s not a universal that software can only be rented with super-intrusive rootkit DRMs.
