Not that fucking Siri canard again. It was debunked repeatedly. The reason Planned Parenthood wasn't being found by the person's query is they were looking for "abortion provider" or something along those lines and Planned Parenthood wasn't listing itself under those terms. It had NOTHING to do with sexism on the part of the developers.
I don't know of the specifics, bit I would have also assumed that since abortion is a slightly controversial issue now, that Apple blocked it. They don't want porn on app store, so I assumed that they blocked abortion providers aswell.
The other reason I find this "siri sexism" theory hard to believe is how the OP phrased the complaint. "... the male programmers didnt think to include abortion ...". Does the OP really think that everything in Siri is hand entered? That a bunch of (men) sat around and wrote out everything that Siri could be asked? The OP knows about search engines right?!
They didn't block it. The actual problem was identified and it was that the person throwing a fit was searching for terms that Planned Parenthood didn't list themselves under.
There was no action on Apple's part, deliberate or otherwise, that caused it.
Shame on the author.
