Twitter 'Unabomber' says all its largest investors want Jack Dorsey to be CEO

Twitter's search for a permanent CEO is now in its fourth month with no apparent end in sight, and there are growing signs of impatience. 

On Friday, early investor Chris Sacca unleashed yet another tweetstorm urging the board to appoint cofounder Jack Dorsey, who Sacca claimed has the support of the company's "largest investors."

Sacca also blasted the board for taking so long and said it should be "refreshed with people who have actual skin in the game."

Dorsey has been serving as Twitter's interim CEO since Dick Costolo resigned as CEO in June. While he is considered a leading contender for the full time CEO gig, his candidacy has been complicated by the fact that he is also the CEO of digital payments company Square, which is reported to be preparing for a public offering in the next few months.

Sacca also addressed concerns that Dorsey could have trouble running Twitter while doing double duty at Square, saying he "has been running both companies for months and both are doing great."

Sacca has been vocal and increasingly critical about Twitter since before Costolo resigned in June. According to a recent Vanity Fair report, Twitter's board of directors has taken to calling Sacca the "unabomber" because of his regular barrages of opinionated tweets that they feel has been destructive to the company's image. 

Pressure is mounting for Twitter to appoint a permanent leader as executives jump ship, morale suffers, and the company's stock gets pummeled.

Here are some of the tweets from Sacca's latest:
