John Legere, T-Mobile's CEO, "crashed" AT&T's CES party, a private Macklemore concert. Apparently Legere had gotten an invitation from Macklemore's agent. After a CNET reported tweeted a picture of him with Legere at the party, AT&T had the T-Mobile CEO removed for "harassing" attendees. There seems to be a lot of commenting on social media about this tonight, most of it positive towards T-Mobile. Another article from The Verge.
