My pet peeves are junk food corporations. Companies like Mac Donald's or Coca Cola have been extremely damaging in terms of public health. And the level of marketing they use to feed people (especially kids) their poison is insane. I know it's pretty unpopular as it can be seen by some as an attack on US culture, but definitely more damaging than Meta in my opinion.

In the UK there are fairly strong rules against advertising junk food to kids.

Of course these are all being subverted on social media because of Meta et al. being uncooperative and pretending they can't identify kids (they know the real age of most accounts even without having to do ID checks).

Fast food and snack companies are the absolute masters of marketing to children. If the United States really cared they'd put a blanket ban on advertising to children like some jurisdictions (Quebec) have done.

Completely agree. Talk about designing for addicted kids
