Yes, it is in the best interests of society to let these corporations run their businesses without regulating speech and associations. That becomes a really slippery slope, where the state starts saying what is & isn't allowed to be said, or who is or isn't allowed to be on a platform. A democratic & free government doesn't generally get to dictate what is said or who someone does business with except for national security reasons. Freedom of association is a pretty common right, even more than freedom of speech (which has limits). The "capturing of the market" that some people are only reachable by that platform is nonsense. There are literally hundreds of physical and digital mediums of communication. Facebook and Twitter are barely teenagers. Twitter is not doing well, and I wouldn't be surprised if it shrank to a niche in under a decade. Facebook as we know it also is not doing well, though they'll take longer.
