Ok i gather from your post that Google, Apple, and Amazon doesn't care who uses their name to make money off them but a small 20.00 bucks a share stock does i live in the real world you might want to rethink this post.
Of course they care if someone is profiting off the use of their name. But Doc said nothing specific about them to his 700 followers and the web domain is inactive. Doc isn't profiting off their names.
Google, Apple, and Amazon don't have any cause of action against Doc. He hasn't infringed on anything.
