What is absurd is finding yourself paying 30% on every digital item purchased on a smartphone app. It would never even occur to us that Microsoft takes a 30% margin on Steam, yet that is what happens on webtoon apps.

Microsoft threatened to take 30% margin on all Steam transactions. That's why Valve embraced Linux and made the Steam Deck and Steam Machine.

Valve already takes a 30% cut of all Steam transactions. It's just corporations fighting to steal each other's revenue streams.

Remember when software was sold in a box with a paper manual in a store? Before App Store and steam, retailers and publishers of games and software also took their share of the revenue from the work software developers created. Their cut wasn’t small.

If the government stepped in to regulate the sales of software (to protect developers and consumers?) do you think: A) apps will cost less B) the government won’t want their cut

Microsoft don't really have an equivalent to iOS so let's compare oranges to oranges: macOS vs Windows.

On macOS, Apple don't take a 30% cut on Steam purchases. Steam take 30% however.

There's a big difference - when you develop an app for iOS or macOS, using Apple's APIs, platform and app store tech, it's reasonable to pay Apple something and they legally can charge.

I don't actually have an opinion on whether 30% or 15% is too much or not. It's factually wrong or illogical arguments that bother me: how can we fight anything when the arguments are just nonsensical.

Apple make plenty of user-hostile decisions, but people need to criticise them reasonably, otherwise they will be ignored by those that might have the influence to change things for the better.
