The video linked in the Twitter thread explains it near the end but I'll summarize.
Rockstar used securom for the original disc release
Razor (an infamous piracy group) cracked the game shortly after release but only for Windows XP (Vista didn't exist yet)
Rockstar released the game on Steam "without securom" but in reality is just using Razor's crack
Fans eventually (like a decade later) realize there's Razor signatures in the executable on Steam
Rockstar pushes an update with a new executable, however this wasn't properly tested and is broken due to how the anti-piracy acts.
The game launches but similar to Arkham Asylum's "broken" grappling hook or Serious Sam's invincible scorpion enemies it messes with the player and doesn't function correctly on purpose.
Really interesting video and once again brings up the ethics of stealing from pirates' works as other comments have mentioned.
Flour, eggs, water, and milk is not a cake, even when combined in a bowl. Sperm is not a person. An egg is not a person. A fetus is the equivalent of cake batter and your mom licked my spoon.
The process for a box is rectangle select tool>(right click)>edit>stroke selection.
If I remember correctly it used to be worse. It was Rectangle Tool, Edit, Selection to Path, Stroke Path
I love/hate gimp but I've used it for years because it's faster and easier than cracking photoshop on a new device.
