Employees of software company Mozilla, best known for its Firefox internet browser, launch a Twitter campaign asking new chief executive Brendan Eich to step down over his stance on gay marriage.

Twitter camapign over CEO gay marriage views

Mr Eich was appointed chief executive of Mozilla - an open source, not for profit organisation - this month, but the appointment provoked controversy because in 2012 it was revealed he had donated $1,000 to a campaign supporting a ban on gay marriage in California.

His anti-gay marriage stance is perhaps even more alarming for Mozilla employees, considering that the company is to some extent aligned with the libertarian, open-source movement.

In response, Chris McAvoy, a product lead on Mozilla's badges project, tweeted on Thursday a call for the Mr Eich to step down.

Mr McAvoy's tweet sparked further calls for resignation from Mozilla employees.

People who do not work at Mozilla got involved.

And then other Mozilla employees began tweeting their support for Mr Eich.

The one person who has remained quiet on Twitter since the furore began is Mr Eich himself. His last tweet, sent on Wednesday, pointed to a blog in which he sought to "lay concerns to rest" over his appointment.

In the blog, Mr Eich wrote: "I know some will be skeptical about this, and that words alone will not change anything. I can only ask for your support to have the time to 'show, not tell'; and in the meantime express my sorrow at having caused pain."
