Facebook. (When Zuck was asked how he amassed so much personal information about people, he famously answered: "They 'trust me.' Dumb f*cks.") Growing up, we were told it was foolish to post personally identifying information to the Internet, then the generation that told us that flocked to facebook.
Credit scores. (Less the concept, namely the fact that they're used so extensively to judge people based on arbitrary rules. It's stupid that the companies behind them are still operating after major breaches involving more information than they should have had in the first place. The average person seems too dumb to care what happens with their personal information, sadly.)
Services like "Grammarly". Some folks noted below that there are some legitimate use cases as an accessibility tool, but the service itself seems to target the English-native people "Oh whatever you know what I meant" crowd, to help them sound smart in emails.
And all this other Ai stuff that seems to market itself on the premise that the user is a complete moron who needs to escape the consequences of their ineptitude.
Almost every Ai commercial features someone using Ai tools to quickly cover up the fact that they forgot their partner's birthday, or quickly cobble together some work memo because they were sleeping or something. (Okay that last one can be kinda based amirite lol.)
Edit: Explanations added because I'm fine being disagreed with but maybe I didn't communicate very well lol.
