it's not shooting the messenger because it's a curated experience to maximise ad revenue
and should be regulated as such
So? Do you think its the only curated experience to maximize ad revenue on the internet (not to mention the non digital world).
If you want to argue underregulated capitalism is bad, by all means, but lets not pretend that there aren't hundreds of websites waiting to take facebook's place if fb's downtime went on for more than a few days.
All the bad people still exist. Its not like fb the platform solely created them or that they will just go away if that particular platform disappeared.
