There are many industries which are inherently hostile to users, insurance, betting, marketing, etc. If you ask people if they feel good about enabling the kind of things these companies tend to do, you probably won't get an answer. I don't think Meta is an outlier here nor are they the only one. Even across other industries you will find many questionable practices in usual operations. If pushing the boundaries of ethics gives a business an advantage, you can guarantee that someone will be doing it, and eventually most will be doing it. It's simply the natural tendency of any system with competing entities. The question we should rather be asking is, how do we tweak the system. What can be done to disincentivize pushing the boundary like this?
The question is how did a social media company end up so shitty it is now compared/it's behavior equated to insurance companies? Insurance companies are required to control payout, and people expect that. The level of stuff Meta does is not required, nor do people think/realize it is as hostile to them as an insurance company.
In the past, people aspired to work at cool tech companies. Devs aren't lining up to work at insurance companies. I never worked in the industry I went to school for because the only jobs when I got out of school were for weapons. At this point I feel the same way about social media, I would never work at such a 'make the world as bad as you can get away with' industry.
