Is this a way for Google to add new sites to their search data and advertising infrastructure?
When you go to the link "Chrome and Other Browsers"(from the website above), it takes you to a page which blatantly advertises Chrome, and doesn't mention other browsers. So Google!
If it was harmless or did only what it says, wouldn't it be handled by a consortium with at least Microsoft, Apple, Google, Mozilla and the like.
History tells us that google looks after googles income.
