3. Targeting -- even under the (debatable) premise that they are intentionally designed to be addictive, cheeseburgers, drugs and cigarettes do not actively target each addict by optimising their properties to their individual addiction.
If I am addicted to smoking, the tobacco industry does indeed try to keep me hooked, among other things by offering me many flavours and alternatives. However, the cigarettes I personally consume are not constantly adjusting their formula, appearance and packet design specifically to satisfy my tastes and desires.
Even a first step of requiring transparency in the algorithms would quickly shatter this stronghold on people's minds.
And those efforts seem effective to me, at least anecdotally. I don't feel particularly bad about those restrictions either.
The problem with analogies to things like cheeseburgers, gambling, drugs, cigarettes, etc., is:
1. Availability -- you have to go somewhere to acquire/participate in these things*
2. Cost -- you have to have money to spend. That is, it's not something you can consume/participate in for free -- you have to have money to spend.
* Gambling is theoretically freely available via gambling apps. But still comes at a cost.
With social media, anybody can do it for unlimited amounts of time, and for free. All you need is a phone/laptop/desktop with internet access -- which nearly every person on the planet has.
Addiction + Free + Widely available = Destruction
