Google, Facebook, Apple and Amazon keep buying smaller companies, and regulators are taking notice

For example, when Amazon began building its cloud-computing business, it went on an acquisition spree, buying at least 13 cloud tech companies from 2012 to 2020, according to the Post’s analysis. That included firms like Thinkbox Software, a maker of cloud-based design tools, and security company Sqrrl Data; in neither case did Amazon disclose the purchase price.
