They will. If Apple doesn't comply with EU Digital Markets Act (DMA) they will have to pay fines of up to 10% of a company's global turnover for infringements. Let them try not to comply lol. Their deadline is on May 2024.
It reads to me they want their own store so they don't need to pay the other stores fees or give them a cut of potential sales. I wonder how many other big tech groups are considering the same.
