You don’t - it’s a bullshit excuse. It’s like a 5 year old with their hand in the cookie jar saying “I didn’t mean to do it.” Yes you did, little Jimmy, what you didn’t mean to do was get caught. Now blow that idea up to a greedy, unethical, billion dollar corporation.
Rhetorical question haha, I know it's bullshit. Popups take effort to create, you can't just accidentally add them.
"Sorry we showed you the ad before the black Friday return window lapsed."
A technical error doesn't result in popup ads. The code had to already be there.
Ubisoft says it was trying to put an ad for Assassin’s Creed Mirage in the main menu of other Assassin’s Creed games. However, a “technical error” caused the promotion to show up on in-game menus instead. Ubisoft says the issue has since been fixed
So they fully planned to roll out full screen pop up ads, it was just supposed to be in the main menu, not in-game. Fuckers.
This is why I don't play AAA games.
