I agree that it has been changing recently, but it has only been changing because now there are a bunch of people trying to actively point it out.
To say so would be completely ignorant of the fact that consumers find the exact strawman you present distasteful. Consumers are not idiots that have to have some enlightened soapboxer pointing out the obvious.
You give the average consumer waaaaay too much credit. Also, you underestimate the ability cultural norms to keep people from thinking about things. Humans simply
don't pay attention to things that are 'normal'. They just don't.
Sure, some stuff that's sexist in games everyone notices even if they don't see it as a problem. I don't think anyone ever thought that skimpy metal bikinis is actually good protection. That's not the sexist part that people are glossing over. It's the fact that women are so often portrayed as sexualized in games and fantasy art that seeing a woman in a metal bikini doesn't get much much notice by many gamers.
Take armor in World of Warcraft. A suit of armor that, on the guys, is shown as large bulky plate mail that leaves nothing but the face exposed shows up on women as a skimpy bit of metal that doesn't even cover the midriff. And I personally know some very intelligent people who
did not even register the sexism of that until it was pointed out. They knew it was sexier armor, yes, but they were so used to the women wearing skimpy clothing in games that the fact that it was Sexist didn't even cross their minds.
So I don't buy your assertion at all.
Some consumers recognize all of this just fine, yes, but a lot of people need it pointed it.
