Apps are bigger than the internet (the web). Apple want to control who can and can't make them and they wamt to control the payment method that yor're allowed to use. if they don't like you you're out. Those are far stronger controls over the world than anything google is doing
Apps are not bigger than the internet, almost all apps rely on the internet! Put another way: if Apple went bust that would be bad for apple users, but if Google went bust the world would temporarily stop.
The google outage last week affected Spotify, Discord, Snapchat, and Cloudflare, and that was only one set of APIs. Google additionally acts as a certificate authority for many of the worlds SSL certificates, so if those CA servers went down every website, service, and app relying on those certificates would also cease to work.
