To me it seems that Twitter is less of a back-and-forth engagement platform like Facebook, Snapchat, or Instagram, and more of a platform for anointed experts/celebrities to use as a megaphone to anyone who will listen. Accepting that, I wonder why Twitter doesn't charge people to use the service to either have a verified account or beyond some # of followers after which it's capped? Celebs obviously get a great deal of value from the service and have the means to pay, so why not charge them? I refuse to believe that there would be a noticeable decline in accounts if you had to pay some fee per, say, 30k followers.
