Because some producers in Hollywood don't seem to understand their audience. Charlies Angels is basically a male fantasy action flick. Three hot, capable women who also happen to kick ass. This makes guys want to see it, and since it has that girl power vibe, some girls don't mind also seeing it.

But, in order to get that extra 1-2% of people who feel they want this kind of stuff in movies, they end up alienating their audience, or just annoying them to the point where they won't even bother seeing it, so they actually lose audience.

You'd think that they would have figured out by now that inclusion isn't raising ticket sales, and the way things are going, it's not even mitigating controversy, because now you just have your past audience complaining. But, it does give Hollywood, or some clueless movie actor, and a bunch of media socialites, the chance to cast shame, so I guess that's worth millions of dollars in investment into a movie.
