I don't know. I think it's easily understandable what they meant by "major". Like, you've heard and probably used, every single one of the services listed there. This is not an official definition of the word "major", it's just a list of services the client is compatible with. They're not insulting a race/religion/nationality, it's just a list of web services you have probably used.
