Nope. It's crazy. You don't go to the most popular restaurant in town and have them tell you to go get desert across the street because the superior food and experience hurt their sales.
Even looking at the commissions fact sheet (Search Engine market share) [0]. 3 of the 4 other companies are billion dollar enterprises. Microsoft decided to make it difficult to switch to Chrome/Google in Windows 10 (no more 1 click). With this consumers are still switching back.
Out of all the bad shit google does, this shouldn't even be on the radar.
For the other end of the story this is an interesting read [1].
