Lol no, did you even read the list? You could pay someone to just search "LinkedIn" and "talent" and "recruiting" on the chrome web store and download each extension. It's probably harder to automate this than it is to do it manually. This is something you could develop in an afternoon and pay a small team of people to do for pennies on the dollar. Even ten thousand extensions is nothing. Spread that over years and this is trivial.
