The former CEO, who is still a member of the board himself, blasted the ‘plots and coups’ that were ‘consistently the dysfunction of the company’.
In a series of bombshell tweets and replies, he endorsed one posting saying that ‘a bad board will kill a company every time’.
His comments come as Musk tweeted ‘Love Me Tender’ as he again teased at the possibility of a hostile takeover of Twitter.
The billionaire posted the Elvis Presley lyrics at the weekend in a potential bid to lure shareholders with a tender offer that could see him seize control.
A tender offer would see him bypass the board and go to shareholders with his offer of $54.20 a share – but he would need to show how he would finance his bid.
He also appeared to suggest he would strip board members of their salaries, saying they would get ‘$0 if my bid succeeds’.
Meanwhile the social media giant filed its ‘poison pill’ defense with the Securities and Exchange Commission in a bid to thwart the Tesla founder.
The plan is being seen as a last ditch attempt to prevent Musk from increasing his stake in the company further following his $43billion bid last week.
Musk, the world’s richest man, currently owns a 9.2 per cent stake in the tech giant and is trying to take it private with an unsolicited bid of $54.20 per share.
But bosses have reportedly brought on Goldman Sachs and JPMorgan Chase to advise it on how to respond to his bid.
Former CEO Dorsey slammed Twitter’s board of directors on as he replied to a series of unfriendly tweets.
Replying to one post on Saturday, he said: ‘When I was fired in 2008 and made chair, the board took most of my shares away from me.
‘I also gave 1 per cent of the company back to the employee pool in 2015. So, ended up with very little of company.’
He also replied to one comment mentioning ‘plots and coups’ in the Twitter board saying: ‘it’s consistently been the dysfunction of the company’.
Earlier in the thread, he replied to a post quoting a ‘Silicon Valley proverb’ by venture capitalist Fred Destin.
It said: ‘Good boards don’t create good companies, but a bad board will kill a company every time.’ Dorsey said: ‘Big facts.’
The 45-year-old entrepreneur is still on the board but is expected to leave when his term comes to an end at the end of May.
Musk’s Love Me Tender tweet on Saturday afternoon was his latest hint he will bypass Twitter’s board and put his offer directly to shareholders.
On Thursday, following a TED talk appearance, he tweeted: ‘It would be utterly indefensible not to put this offer to a shareholder vote.’
He later added that the board’s ‘economic interests are simply not aligned with shareholders’.
This morning, in a raft of tweets, Musk slammed Twitter’s board, blasted those claiming his bid could not work and also praised an article in Bloomberg.
Managing Partner at The Future Fund Gary Black had tweeted: ‘Let me point out something obvious.
