What Amazon acquisitions have put other companies out of business? Amazon bought Eero, yet I haven’t seen other WiFi router companies go out of business. Amazon bought Ring, then a competitor was so successful that Amazon bought Blink. This notion that Amazon’s acquisition would put competitors out of business seems to be a weird dream. Especially when it is known an easier path to “unfairly compete” would be to just create an Amazon-labeled robotic vacuum and put that on the market.
