Amazon's private label business gets controversial

Amazon says its private label products generate only about 1% of its total sales.

Amazon's private label strategy was a hot topic during a CNN Town Hall this week featuring Sen. Elizabeth Warren.

According to Business Insider, Warren criticized Amazon during the Town Hall for its role as both a marketplace for selling third-party goods and as a direct seller of its own private label goods.

According to Business Insider, Warren's chief criticism is that Amazon could use the data it collects from acting as a platform for third-party sellers to help its private-label business, which would enable it to unfairly compete.

In a response, Amazon tweeted on Tuesday that it does not "use individual sellers' data to launch private label products."
