Fuck Rockstar. I changed my email accounts a few years ago but forgot to change Rockstar first. This wasn't a problem. Now, after buying GTA V on Xbox and Steam and sinking a lot of time into it over two accounts, they added some mandatory launcher on Steam that forces you to login to their Social Club. Mandatory launcher calls an account that I can't unlink, triggers mandatory 2FA to an email that doesn't exist. They refuse to help despite my willingly handing over a lot of private information - their support system is as good as fake. The end result is I have sank >£100 in buying their games and they ensure that not only do I not get to continue my account on GTA V, but I have been permanently locked out and actually impossible to play any Rockstar Social - walled game on Steam.
Partial 'correspondence' of my third attempt to get help from them. Twice they ignored the support subject.
Judging by other complaints online this exact issue has persisted and screwed over players since the creation of GTA V, so at least 12 years.
I have the same issue with Activision, and here's the kicker. They're exactly the same blueprint. Same support. Same result. Same fake-ass Western names on their signature.
I feel like Rockstar needs to be continuously pressured, injustices talked about, just in case they give.
Just don't give corps like Rockstar money.

I emailed Rockstar and started a request ticket and they want me to log in to get me to reset my 2FA which is preventing me from logging in.
THIS IS PEAK CLOWN WORLD I CAN'T BELIEVE SOMEONE ACTUALLY GOT PAID TO IMPLEMENT THIS JOKE OF A SYSTEM
Edit: For the time being it seems they have disabled all support as none of my support requests are going through, even with omitting data and using VPN multiple times.. I've had seven unsuccessful tickets and was just brainstorming how to automate the requests.
Final Edit: Thanks for your responses everyone, looks like legal is the only route. After 24h my support requests are still being auto blocked (not submitting as there's no delay before response), and I am skeptical they switched off support for that long, even if it is fake, so they just blacklisted my details I think.

Mandatory launchers can fuck right off. I was lucky enough to get Rockstar support to accept my Steam purchases but even then I had to try twice because the first time they pretty much blew me off.
I also had a similar issue with Ubisoft. There it was actually easier to restore my old email than get Ubisoft support to cooperate.
In short, fuck forced launchers and anyone who says "it's just another account". Yeah, it is at the moment but who knows 10 years from now. You'll be locked out of your games because some fuckery happens and support won't do shit.
... Iike Steam's? 😛
You know what I meant. If I buy a game on one launcher it shouldn't open another launcher that then launches the game. The other launcher is completely unnecessary but it is mandatory to launch the game, hence mandatory launcher.
Edit: just to make it clear, if I make another account on another store that IMO is fine. I don't have a problem with having steam, gog and itch accounts. But when I buy a game on one storefront/launcher and then I have to make an account on another storefront/launcher to play the game I already bought, that's bullshit. In OPs case he was forced to make an account for a game he bought elsewhere and is now being punished because the company is stupid.
Oops, I misunderstood and agree; I didn't realize a second launcher was the issue here. That is messed up.

I am aware of this list. Try comparing it to itch.io and GOG, though.
Think the complaint is where a launcher is required on top of a launcher. Like if you buy Cyberpunk 2077 from Steam, GOG, or Epic it doesn't required another launcher on top of the launcher you bought it from.
Good thing is that it does seem like majority of games don't do that. Even EA is moving away from it.
That's not the best example, because CP2077 has its own launcher (at least the steam one)
--launcher-skip
And I'm talking about launcher the type you have to log in again.
Example being Ubisoft games where you get it from Steam or Epic and then have to install UPlay and then log into UPlay.
I'll even use Finals as an example which isn't DRM free. You install on Steam and go on playing with no additional login into a secondary launcher. Or you install from Gamepass with no additional login for a secondary launcher.
