Source? the FAAMG plan with horizontally scaling the business into more markets is ultimately "benefit the consumer", so disallowing such expansion is effectively making products worse (for the majority; the minority customers unhappy with the new FAAMG-backed competing product do indeed suffer). If this policy is that narrow, they'll just slow acquisitions/product development and either start spinning off more companies or increasing VC spending, which doesn't move the needle besides detaching the company's name from their money.
