> Then are these network effects worth paying 30% for or not? If yes, you've just conceded the price is fair. If no, then Purism's Librem exists (and will not be bought by Apple).

EU forcing Apple to lower app store fees to 5% or something similar wouldn't remove the network effect though, there is no incentive for EU to allow Apple to extract that fee. Tell me this, what would EU lose by capping App store fees in general? App stores would still operate there, App store companies would still be very profitable, they would just be less of a leech on the economy.

> The same way it gave small railroad companies a chance? Or small oil, or small pharmaceutical, or small telecom?

Regulating those companies greatly reduced their ability to extract money from the market and therefore contributed to the plethora of small companies in other domains we see today. We don't see small companies in oil or pharma since those domains requires scale, which is why we instead of forcing competition force regulations on them to make them do the right thing.

I mean, imagine if we let the oil companies take 30% of GDP as revenue, it would totally ruin the economy and prevent us from progressing as a society. You could argue that those oil companies deserved to get that much money since without them how would we get to work? But, fact is that giving large companies that much money doesn't benefit anyone but their shareholders.
