I think the issue could be that it’s forcing the companies to include it, even if the company can include alternatives as well or when user can just ignore it. Not a lawyer, but back when Apple was in the courts I heard social media lawyers saying that Google actually had a worse prospect because when you force your competitors (other non-google phone makers that use Android forks) to bundle G Play/Services it can be considered “tying”. Then if a company just uses the GPL code without following the contractual rules like that they can’t advertise Android and it it could hurt their market share.
