Browsers should have pay/tip button to support website owners. And browser vendors should handle the payment. This would limit ads and tracking as well which aligns with Mozilla goals. Can I pitch this idea to Mozilla somewhere?
But they don't have the infrastructure to reveive the payments internationally,(apple and google do) but there wouldn't be a conflict of interest for example google with their ads businesses and imagine apple charges 30% for every transaction like the do on the apple store
You're describing Brave
Browser companies can't handle payments unless they decide to pivot to becoming a payments company like PayPal.
The API and standards talk in the article is putting the cart before the horse. There is currently no way to send money peer-to-peer without an intermediary that can handle the bank transfer, and intermediaries tend to charge a lot for this service.
Because of this, the best options are to add a PayPal or Ko-fi button on the site, with the understanding that the publisher won't be receiving the full amount you send.
