I think that depends on Twilio's knowledge and intent. If the specific purpose for suspending services was to allow unauthorized access, that's conspiracy.
It'd be as if a bank's security guard quit and walked off the job the day of a bank heist. He has the right to quit, but not a right to coordinate with the robber and leave his post for the purpose of assisting in illegal activity.
The latter is also conspiracy, and a stretch at that. What would Twilio gain? The most likely explanation was that everyone ditched Twilio as a customer and the remaining skin was quickly pecked off by vultures.
