There's plenty of talking points to consider:
(1) On the surface, the video is merely telling men not to engage in toxic masculinity. However, to anyone spending an iota of time on the internet, it should be readily apparent that this attack on toxic masculinity is heavily contextualised by MRA talking points that are largely ignored outside of the internet. Facts such as the astonishingly small rape rate (albeit, rape is incredibly difficult to prove), false rape/sexual harassment accusations going largely unpunished, the extreme broadening of the definitions involving sexual assault (with things like financial/spiritual abuse counting) etc., are all ignored in place of a boogeyman (rape culture). Given this context, I am not surprised the backlash the ad received, and I can't blame men for feeling so betrayed by Gillette.
(2) You have to wonder, after seeing other companies shoot themselves so thoroughly in the foot, why Gillette would choose the same path. There was likely extreme external pressure to run these suicidal ads, elsewise they wouldn't have done it. I find it nigh impossible that they didn't understand they enormous backlash they would receive for running these kinds of ads.
(3) Should companies be involving themselves politically like this? Companies like Nintendo have literally said that they don't want to be involved in politics, but instead want to create a product that will be enjoyable (and sell well). For any company that isn't pressured by external forces, it seems impolitic to meddle with affairs that go well beyond the product.
(4) Personally, I didn't like how the man told the boys to stop with the rough-and-tumble play. I know there are other dislikeable traits about the ad (one guy stopping another from talking to a lady on the street), but this one is personal to me. As a primary school teacher, I see other teachers stop this play all the time, and it damages the kids. They don't develop a conception of healthy boundaries. They don't learn to distinguish from real and fake threats. It warps their social perceptions for the worse. Even young girls like to engage in this behaviour, to some degree -- it's perfectly normal behaviour.
I could write further points, but that's sufficient for now.
