Well, we would need data on how many parents complain vs how many parents buy a strongly gendered toy when an less gendered alternative is available.

Because, you know, anytime something politically incorrect happens, someone will complain, and maybe even write a clickbait article. But how do people vote with their wallets?

I admit I don't know. Situations like this often seem to me like chicked-and-egg problems, where producers say "we have to make what people buy, and people buy X", while consumers say "if it isn't in the shop, I can't buy it, and the shops usually only have X".
