So there are two different categories of things here. One is, they ban cannabis and put individuals in prison for it, but then if you pay thousands a year for overpriced health insurance and the insurance pays thousands of dollars for a doctor to ask you some cursory questions and a pharma company to manufacture the drug, you can get a prescription for opioids, which are way more dangerous. But that isn't the big guys violating the law, it's them following a law that they bought and paid for. That's bad in a different way.

The relevant thing here would be that they pass excessive copyright laws, but then Meta violates them and maybe gets away with it because they're doing it in a sympathetic way and the government doesn't want to hamstring emerging industries in their country, whereas if an individual would be sued into oblivion even if the thing they were doing was equally sympathetic.

Because it's not just about the public noticing it, it's about the public noticing it in time to do something about it. If an individual gets sued or arrested, they're immediately screwed and will be under pressure to settle or plea bargain before they're bankrupted by legal fees. But once they do, the case is over. Whereas large companies can fight, or pay lawyers to stall while they wage a media campaign to counter the usual imperious press releases from the prosecution, or use their money to lobby the government while public opinion is in their favor.
