No, it’s misinformation and people who uncritically repeat things without verification.

I’ve had the game installed for years and have to manually apply updates, there hasn’t been one. e: I just checked, last update in Steam is dated 2022

All they’ve done is make their TOS universal across all of their games.

e: adding this from last post. TL;DR: People are spreading misinformation

So, let’s look into the claims.

Here’s the TOS:

There is nothing about root level access.

In addition, if you look at the patch history for Borderlands 2 on SteamDB, you will see that the last update for the game was 4 August 2022.

So, to be clear: There is nothing in the TOS that requires you to submit to a rootkit and there is no spyware that has been added. The comment in the OP is simply wrong.
