The event staff fucked up thinking they were ejecting some no-name punk. This young man has a platform and the ability to do damage to campaigns that are afraid to answer tough questions and who instead toss out the people asking them. He's built up a following online and has made a bit of a name for himself in New England.
Am I the only one who thinks it's crazy that the only grounds they have are that HP didn't disclose that their All-In-Ones won't let you scan or fax without ink and not, you know, the fact that they do that in the first place? It should be illegal to disable critical functions of a device simply because an unrelated function is temporarily unavailable. There's no technical reason HP is doing this other than, "fuck you, buy more ink."
