The smaller company feared that complying with the demand would violate customer privacy, said a person familiar with the episode.
Ecobee’s devices work with Alexa, Amazon’s voice-powered assistant, and it already shared some data with Amazon, the person said.
Moreover, the company worried Amazon would glean insights from Ecobee’s users that it could use in competing products.
Amazon responded that if Ecobee didn’t serve up its data, the refusal could affect Ecobee’s ability to sell on Amazon’s retail platform, the person said.
Partners often acquiesce to Amazon’s demands, the executives and officials said, because of its power in a range of market sectors.
