It goes back all the way 2010, I remember opening up chrome to try it, right clicking on a youtube channel background to attempt to download like I could on firefox just fine, and it not having the option, why would you go out of your way to restrict a user easily being able to right click and download? well, because you believe you own the web.
Never used Chrome and never will, if you use Chrome you are actively making it worse for yourself in the future once they implement enough bad policies that it becomes near impossible for almost anyone or anyone to bypass their restrictions.
