YouTube is reportedly slowing down videos for Firefox users

It it legal? I remember when China's tech giants started infighting and the party ended up dividing them and phorbiding them to do so.

They where creating tech exclusive for their devices and internally block all other out.

I just figured if we aren't doing it here there should be a reason. (Apple appart)

Edit:guys what I'm saying matters the orthographic mistakes can be easily attribute to my lack of interest in writing the proper queen's English when any shit will do
