Modern consoles are pretty great about backwards compatibility. There’s room to improve for sure, but an Xbox Series X/S can play all Xbox One/Series games, plus hundreds of 360 and original Xbox games. PS5 is a bit worse with only PS4 backwards compat. The Switch is in the roughest shape, because PowerPC emulator or hardware compatibility wasn’t practical with the design or hardware of the original Switch.
“Gentleman’s NDA” is not a thing. It’s either a legally-binding NDA or it’s not. It’s within Valve’s right to ban him from the game but saying the game shouldn’t be covered at all is silly.
If every news outlet avoided a topic because the company wouldn’t outright confirm its existence, we would never have reporting based on leaks and rumors. That’s dumb and would make journalism worse for everyone.
If Valve wants to be shitty about it, that’s within their right (unless they want to sue, which would be difficult to defend in court without a written legal agreement). It is also true that other outlets are free to do handshake agreements to not cover the game. The Verge didn’t break any rules, and Valve already maintains a minimal relationship with the press, so not talking to The Verge probably wouldn’t change anything.
The rest of the industry uses embargo agreements with mutual consent if they have private information. This doesn’t change anything for other game companies, unless they also want to do private-but-not-private beta tests.
Valve barely talks to press anyways, in a very similar fashion as Apple. At worst, maybe The Verge won’t get a Steam Deck 2 review unit ahead of time or something.
That’s not how this works. The Verge didn’t break an NDA or embargo because they didn’t get either of those things. Valve allows random people to invite other random people to play, with just a “pretty please don’t talk about this game” warning. There was already people talking about it online and leaked footage.
