They reached out to Verizon privately, a Tier 1 carrier with expectations and responsibilities as a good netizen, and got no response.
They attempted to reach out through Verizon's public forms of communication and got a bullshit irrelevant CS response despite requesting escalation.
They then called out Verizon before the community as a whole.
They don't have the luxury of waiting for a well prepared letter from some Verizon lawyers. Modern day customer expectations don't allow for it. You may call it trolling, but all I saw was a company asking another company to stop pissing in the public pool.
