I thought of this, but I think it's OK in the context of the joke. (And technically, Speedo might stereotypically be associated with men, but they make stuff for women too.)
No, I don't think so. There's a tendency in tech circles to act like programmers etc. are just men. It's not malicious but it makes women feel invisible, which is a factor in the gender imbalance in tech. So as part of the effort to get more women into tech, we're self-conscious about thoughtless (not generally malicious) actions that make women feel less welcome. I would definitely consider a serious headline saying "grab your speedo, we're sending you to Brazil" as unintentionally making women feel forgotten. But again, since it's a just a joke about a photo, it's not really a problem in this case.
