You're at least right about one thing. Large tech companies will always exploit opportunities to limit the user, which is a privilege Apple has abused for too long. It's time for computing to be democratized again, even if we need to drag Apple though the mud to get there.
I don't know if you realize this, but OP and you are saying the same thing, they are just saying it slightly different.
You: To stand up to large company bullying you need to regulate them through the government.
OP: To stand up to large company bullying you, you need another large company who has the pockets and sway to bring change through congress because our government is bought and paid for by corporations.
It's regulating your iPhone so you don't have to?
I really don't want idealists to mess up the iPhone's stability, performance and security so people can use the minecraft app store or whatever.
You can’t walk away from government regulation because there is ultimately a gun at your back. Governments do not give up power once they’ve received it. Governments change hands who may wield that power differently than when it was imagined to be when first received.
People in European countries have had to learn this the hard way many, many times over and yet still don’t get why other cultures might take a different view on it.
The government is the one institution in most people's lives that they have a real say in, and probably the only one that affords them democracy. I doubt any of us sit on Apple's board.
The problem is that the Apple and Google duopoly is stifling choice and competition such that we can't realistically walk away from those companies. Market forces haven't solved this issue, and this is where antitrust legislation kicks in.
Just because smoldesu says “Letting software go unregulated didn't work, full-stop” doesn’t make it so. It doesn’t even make sense–you’re the one fighting for deregulation here.
Discoverability and the ease of access that the playstore/appstore provides is enough to pretty much always want to have your app up there.
The main difference is that there are a lot of apps that are simply not allowed in the appstore or that you need to change substantially to comply with apple's rules. For example, Telegram has censored content if you download the app from the appstore given Apple's pornography laws. Other apps that might be used to infringe on copyright are outright not allowed (they're also not allowed on the playstore, but you can install them from the apk or a third party store).
Now, maybe you think these restrictions are appropriate and that's fine... for you. Other people might want the freedom of doing more with their devices that they paid hundreds and hundreds of dollars for without having to resort to extreme measures. The argument Apple uses is bullshit and the EU saw through it.
