> So there is no reason why they cannot do this tomorrow without the paywall
Sure you don't when you are dismissing economics of software development so vigorously. Try to look at things from the perspective of economic incentives, not pure technical standpoint. You'll understand why free platforms are way less convenient, and closed platforms are as they are.
The incentives can change through eg law as forest_dweller has already mentioned in his comments. I think most people "understand" the current economic situation works out quite well for closed platforms, but it doesn't mean a better way does not exist and can work out just fine economically
As I said if it has to be mandated legally through a movement similar to right to repair so be it. The incentive will be "you must follow the law or be sued".
