T-Mobile TMUS CEO John Legere is by and far one of the most interesting CEOs on Twitter TWTR not only for his personal content, but how he often goes after wireless carrier rivals Verizon VZ and AT&T T .
In the battle for more phone subscribers, Legere will never pass over the chance to poke fun at the competition. With over 4 million followers and counting, he certainly knows how to elicit a reaction. For example, that time he went after Verizon during their April earnings miss on the highest day of the year.
