> Apple and Google quickly built up their duopoly such that everyone doing anything with mobile phones has to pay them a tax.
Long before Apple and Google made phones, a huge mobile device ecosystem already existed, including app stores, and it was way more locked down and expensive than what we have now.
The iPhone did not even launch with an app store, its launch concept was 100% web apps. They only added the native SDK and app store after developers and customers demanded it.
Again: I know the world is different now. But the idea that this was all some swift inexorable coup by Apple and Google is totally inaccurate. Plenty of other companies had a chance to do things differently, many with huge head starts.
