Lets put aside the events that this suspension is targeting and just focus on the statement of business making a business decision about their private property.

Lets put aside the events that this suspension is targeting and just focus on the statement of business making a business decision about their private property. Why is there a difference between Twitter, Inc making such decision and Verizon Communications. Neither are government. The only reasonable argument that I can think of is that Twitter holds less of an monopoly to their users than Verizon. That however seems to me as up to interpretation, and not about the question about what is or isn't private property.
