WITH FRENEMIES LIKE THESE

In the olden days of tech (like, 15 years ago), Steve Jobs said Microsoft had "no taste"; Larry Ellison suggested that one rival executive must be "on drugs." Now a new generation prefers to make nice in public and withhold their acrimony for a private room in SoMa. Here's a rundown of the squabbles

EVAN WILLIAMS vs. JACK DORSEY

Both men sit on the board of their progeny, Twitter, but they aren't as close as they used to be after ousting each other from the company. At one point, they even stopped following each other on Twitter.

MARK ZUCKERBERG vs. EVAN SPIEGEL

Few people would turn down $3 billion from the Facebook founder. But most people aren't Spiegel, who has turned Snapchat into one of the world's top social platforms.

MARC ANDREESSEN vs. BILL GURLEY

The V.C.'s don't agree on much. Andreessen disavows a bubble; Gurley says it's real. Also, according to The New Yorker, Gurley once tried to get Andreessen's partner to cut him out of their company.

TRAVIS KALANICK vs. LOGAN GREEN

Kalanick, the co-founder of Uber, is an aggressive guy. This year, he tried to recruit drivers away from Lyft, Green's competing ride-share service. Lyft also accused Uber of canceling its cars.

TRAVIS KALANICK vs. LARRY PAGE

The two men may be partners—Google invested $258 million in Uber in 2013—but the bond seems to have frayed behind the scenes. Google has reportedly been mulling its own car-on-demand service, and Uber has been investing in self-driving cars, Google's bailiwick.
