Yes. Target the algorithms, not the method of delivery. Hacker news also counts as social media, but here we all are seeing the same feed on the same site with minimal (if not zero) tracking to try and extract info from the audience.

Even a first step of requiring transparency in the algorithms would quickly shatter this stronghold on people's minds.

Indeed. In fact, you may notice I explicitly left out gambling from the list of 'non targeted' addictions. The reason for that is that the delivery methods for gambling cover the whole gamut from zero to fully personalised targeting, and I didn't want that to distract from the point.
