He is saying that any hit not on the first two pages of google's search results, doesn't exist, and is therefore being deplatformed?
That's a ludicrous position. Those hits do very much exist, and google will display to you each result in turn hoping you find something to click on. If his argument is taken at face value, the vast majority of hits, on every search term, for every user, is being deplatformed. That's just not the case. You can't really say you're being deplatformed, because you're not on the first page.
