This is going in the wrong direction. Government shouldn't be imposing regulations on monopolistic app stores when competition can naturally break the monopolies and bring them in line with developer and consumer needs. Let there be multiple app stores, charging developers competitive fees and implementing competitive security and convenience features. Don't let the platform favor any particular app store, or raise barriers to app mobility between stores. See how long 30% fees and hostile policies last when any developer can just upload their apps to another store with minimal modifications, and any consumer can easily use that store.
What you are suggesting is applying the same logic to App stores that they're applying to payments. That's more likely, not less, if this legislation goes through in SK and gets copied by other countries. So, same direction.
FWIW, I think payments are an easier place to make progress. It's hard to imagine an alternative app store taking off in response to a single countries' laws. Even if it did, a diverse app store market kind of negates the app store concept entirely. At that point, you may as well return to the old ways.
Alternative payment options will be immediately utilized by devs. The market can support lots of them, and prices will quickly respond to competition. If users and devs have choice, market prices will be nowhere near 30%. I'd be surprised if it's >10% for long.
While different App Stores is preferable, this actually is a big improvement for users and developers alike
Many users simply don't want to share their payment details with App Stores because they don't like "one payment serves all" setups. They want to be asked each time for their payment details because they feel that gives them control
Likewise, many users already have payment arrangements with providers like Paypal that they trust, and don't want to add one more trusted payment provider to their list
As a developer, I want to offer all options to users - App Store payment, Paypal, CC, and anything else
So I like where this law is going, and I have no doubt it increases the chances of other legislations imposing further "restrictions on what is not allowed" on mobile devices
That lowest common denominator already exists in official app stores. There are huge swathes of garbage apps that try to scam you with expensive subscriptions/MTX, use shady ad networks that push more garbage apps on you, ask for every permission under the sun for no other reason than to collect data on you, etc.
