I have to pay the Apple tax to reach my customers where they are, iOS.
I have to pay the Google tax to reach my customers where they are, the web dominated by Doubleclick and Google search.
Do you care that a tech company is extracting huge sums from digital markets or do you just care how? Does it make a lick of difference that with ad spend it feels like you're buying something or when you put ads on your site you never see the money they took off the top?
Everyone should care how! The how is the important part.
If there are alternative ways to access something then people are free to compete of product. That's a huge difference because competition is generally consumer friendly.
If Google starting charging site owners 30% of their revenues to index their website on Google Search, and there was no possible alternative, the EU would probably be looking at them pretty harshly too.
Technically, all pounds of flesh are the same mass :)
I can send you my Android app, no Google required.
I can’t send you my iOS app without relying on Apple.
