The most recent ones I've noticed are Riders Republic and Borderlands 2. Helldivers also introduced a bunch of new microtransactions years after it's launch.
So it's the fault of the delivery-device? Why didn't you make a backup of an older version just in case?
Besides, last time I checked, you can. With a bit more hassle.
All not the case for a "live" online-game. Which borderlands wants to be.
If BL is "exactly the problem". And GOG does it better. Why is it still steam's fault? Use GOG then? Where is it the delivery-device's fault?
As BL2 offers online-coop, and is also the major selling point of that game, a fragmented market is impossible.
It doesn't matter if you prefer offline or not or that you CAN play solo, it is online coop. I never played it coop either, but that's what it is and hence everyone has to have the same version. Simple as that.
Point with gog was that they do it better. Vastly so. Yet only a tiny fraction of devs choose them. Hence it begs the question whether it's the platform's fault per se.
It only matters in the sense that you're allowed to not purchase online games.
Virtually every game in existence has some sort of online element. But what you seem to be unable to grasp is that many of them have single player modes that don't require any internet connection.
It's as simple has having a server that checks the version of the game installed before allowing access to online services.
