if you don't like this thing we're talking about, why didn't you do anything to stop this other tangentially related thing that happened a long time ago?
I'm not even sure what you are describing makes sense. our supermarket sells hood brand milk, as well as their own private label milk. however the private label version is made at the hood factory using hood milk. in this case, I'm pretty sure the people at Hood don't care which one you buy since they get paid for making the "ripoff" brand.
your example would be fitting if Apple made their own clone of epic's app, but paid epic to do it
While that may or may not be the case in this particular anecdote, it's certainly not the norm.
It’s like there’s only one supermarket where you can sell your products, but they can still compete with you as you described.
Compare that to app stores: users are in practice not free to pick another app store, even on android - network effects make using alternatives quite tricky and even risky, and the device/OS maker don't make it easy to pick reputable alternative stores. App stores additionally leverage their monopoly on that user to hide their costs from them; e.g. in apples it's not even allowed to mention the cut apple takes and where you might be able to buy more cheaply - and not just in the store, but even in the app itself, even indirectly! There's no MSRP by which to note that that 30% cut is extortionate. Finally whereas last-mile logistics are tricky for real-world goods, app store checkouts are not; almost the entire value provided is in network effects: i.e. the value is provided by the users of the app store, not the app store itself.
All of these disparate factors mean that app stores clearly are not a competitive market, whereas supermarkets aren't quite as bad. But let's not forget: just because supermarkets are "less bad" than app stores doesn't mean there's no potential for market manipulation; we should be vigilant there too - just that the kind of manipulations supermarkets can pull off aren't going to be quite as impactful.
TL;DR: not only are app stores much, much worse than supermarkets when it comes to harmful market manipulation, flaws in one market do not excuse flaws in another anyhow.
Says who?
This is whataboutism.
Many people around here were not old enough to be interested in politics "literally decades ago". And for those who were, the hindsight we have now is a good reason to start getting interested in the issue.
> It's a store, expect the store to take a cut and if you're too successful, compete with you.
The whole point of politics is to fix outstanding issues. "It's always been like that", "suck it" or "fuck you, got mine" rarely make for convincing political speech.
The issue here is not making a comparison, but calling people out for not having addressed the object of the comparison beforehand.
Here in the UK, a common tactic of theirs is selling a branded product, then if it sells in sufficient quantities they make their own brand, cheaper, sometimes lower quality, version.
And then they put it right next to the original product on the shelf.
It can't be one rule for the tech companies, and another for all the other companies. It's a store, expect the store to take a cut and if you're too successful, compete with you.
