Effect size matters. A lot. I haven't seen any convincing arguments that Facebook is even as bad as the classic "couch potato" TV junkie scenario. It's impossible to prevent someone from making bad decisions, so the size of the downside risk has to be strongly considered before claiming a problem is worth heavy-handed fixes.
People behave differently due to new technology, sure, that's a given. Is it catastrophically worse than easy access to extremely potent drugs? The outcomes suggest no.
Some people use "it releases dopamine" like that's a bad thing, like our bodies weren't wired with dopamine receptors to teach us how to function in a society. Are you proposing we get rid of everything that releases dopamine? We should all live a bleak and meaningless life?
Humans are social creatures. We're wired to seek positive feedback from our peers. Getting a laugh in a face-to-face conversation is no different than getting a smiley face in an SMS is no different than getting likes on Facebook.
Obviously not, but you believe gambling can be addictive right?

This means your argument isn't over whether or not social media (or other dopaminagenic activities) are or aren't addictive. You've conceded that point. Which ryandrake had expressly rejected another two posts up:

The question is whether or not they ought be regulated in some way.
I'd also focus far less on the specific mechanism (though gambling, drugs, social interactions, and A/B-tested sticky-on-page highly-habit-forming social media all do, as you've explicitly stated, rely on the same chemical mechanism), and instead, in the resultant behaviours.
I'm well aware that etymologies are neither clinical diagnostic tools nor necessary indications of present use. I still find them interesting in informing a discussion. And the etymology of "addiction" is a case in point:
c. 1600, "tendency, inclination, penchant" (a less severe sense now obsolete); 1640s as "state of being (self)-addicted" to a habit, pursuit, etc., from Latin addictionem (nominative addictio) "an awarding, a delivering up," noun of action from past participle stem of addicere "to deliver, award; devote, consecrate, sacrifice" (see addict (v.)). In the sense "compulsion and need to take a drug as a result of prior use of it" from 1906, in reference to opium (there is an isolated instance from 1779 with reference to tobacco).
Same point. Same goalposts. Same location. Feel free to disagree, but I know what I wrote.
I mean, what does Heroin do to your brain? Releases a ton of extra dopamine and serotonin and crap, right? And what happens when you see that 14 people liked your post?
Okay, so maybe Facebook doesn't change the way that your brain's receptors work with long-term use, but don't deny that people keep going back for that hit of inclusion.
