Who decides what is unrelated or not? Amazon's whole retail business started by selling paper books. Extending that to kindle and audio books doesn't seem so outrageously "unrelated". Its more of an ecosystem which has legitimate benefits to the consumer. And once you have audio books, music and video doesn't seem like a huge stretch.... etc etc. Apple is the obvious example of this. Do you think every single service apple offers should be broken into a separate company? Apple pay, apple music, icloud all seem to be "unrelated" but the consumer legitimately benefits from these things being bundled into a cohesive ecosystem. Breaking these things into individual companies which has to be profitable based on just their one product would lead to higher prices and worse user experience, IMO. For non-consumer facing products, the case is clearer. AWS / GCP could be split out nicely. The ad networks of meta and google could be independent without hurting the consumer at all.
