This is not equality. This is not feminism. This is just unintelligent and illogical bias.
So Ello was founded by men, that doesn't mean it was made for men and not women. Ello is a social space created (I believe) for creative people by people who care about it's users. Never have I been in a more socially accepting or positive space, where creations flourish and expression is encouraged.
On a pedantic note: life must be extraordinarily hard boycotting everything which was invented or founded by men on this seemingly weak ideology. Following this post, this human also can't use most (if not all social media), email (the actual concept as well as most web based email sending software) or google. Going further they must find life without televisions, lightbulbs, bicycles, contraceptive pills and computers a challenge. Also no more free health care; the NHS was formed by a man too! Oh yeah, and cars, mobile telephones, tin foil. No coke (or even pepsi), wrist watches or flu vaccines. No radio or enjoying the surrealist art movement (damn Breton being a man). Say no to Gucci, sony, nintendo, instagram, YSL, toilets and movies, vinyl (or CDs), cameras, peanut butter, iPods and aeroplanes.
