Possible translation: after a lot of people with nothing better to do took offense at a tech article, I took it down because: 1) I don't want to be hated, 2) I don't want to lose my job, 3) I can't be bothered to even argue against the flock.
It might not be what Ryan means (I can't speak for him), but it sure is what many people mean when having to take down something because of PC complaints.
This thing is getting out of hand. It's the first world idea of a "cause" by people whose idea of "revolution" and "making society better" is blog posts and twitter snark.
The very first programmer was a woman. For a lot of time, computer operators were mostly women. There are not many things stopping women at entering IT, and sexism sure is not one of them. Women thrive at other places with much more deep and inherent sexism (or, to put it better, with actual sexism, instead of mere tit jokes, which is what is mostly mistaken as sexism in the tech community).
I attended uni 15 years ago for Comp Sci. On my year we were like 70% men and 30% women. Not because they feared for sexism (actually there was nothing of the kind -- students were either good or bad at lessons, regardless of sex). We all had fun together, in large mixed groups. Sexism never was an issue, and I've never heard any woman complain about it in the university. Other fields were like 70% women 30% men (Applied Math, Medicine, Biology, etc). Men mostly wanted to get into comp sci because they liked games, programming and this internet thing already. Women avoided the Comp Sci not because of some fear of sexism and such, but because it was considered to have bad work prospects (times/salary/etc), whereas biology was considered to be "blooming" at the time.
