Being a gatekeeper to something important is sufficient. If Apple and Google both consider you a persona non grata, you will have a tough time getting by when the businesses you use daily (let alone government agencies) start insisting on interacting only via an app. Meta does that, and businesses that use only Facebook, WhatsApp, Instagram all suddenly can't see you.
Similar effects with money, though at least PayPal is no longer really a gatekeeper.
