The risk of personal identification due to IP I can buy into; the risk that your already public IP may be exposed to a do-bad-criminal who wants to exploit you via Discord.. feels no more dangerous than having a vulnerable computer connected, anyway.
With near unlimited time on their hands, and an information rich internet, they can find how to start pentesting.
Blind devotion to a cause and a flexible mind can overcome many problems.
Too bad Valve makes money now and not games, they can't even get a fix out after it's been disclosed for years.

Titanfall (the original) is another one (also Source Engine underneath but rewritten by Respawn/EA), a salty hacker who was mad he was getting rekt has been taking down the multiplayer service off and on for years now.

Last I heard he was starting to hit Titanfall 2 xbox servers too (since nothing has been done after years attacking the first one, why wouldn't he escalate it further?) and Respawn just don't care, they're done with it, they make piles of money from Apex now and don't care about supporting their older stuff.

Given the clientele of this website, hoping a little name-and-shame might bring some attention to the issues...
Once a game is sold, there's not much of an incentive to keep it alive other than making sure it's moderately playable so that they manage to sell expansion packs or downloadable content. A hypothetical "someone might overflow a buffer and run arbitrary code" bug is going to be pretty low on the list compared to "all the graphics are broken on the latest nvidia driver because our code base is held together by duct tape and wishful thinking."
Even for the developers that do care about writing decent code (and a lot of them do care about making great games), after 60 hours or more a week of fixing random bugs on Barbie's Plastic Adventures, Call of Battlefield, or Mobile Lootbox Idle Clicker, there's not that much motivation left at the end of the day to work on these kinds of issues.
Even Rockstar had the issue about load times for GTA online, which had they even bothered to look into it, would've netted them dozens of millions of dollars.
Until there's something absolutely catastrophic like a worm that spreads through a popular online game and formats hard drives/mines bitcoin/transfers all the hats to third parties, the industry will keep on doing the same thing as usual with no care. I wish it was different, but it's not, unfortunately. I definitely understand your frustration though.
