Apple has not, to my knowledge, required OEMs to bundle Safari with macOS alongside threats to withhold macOS if they don’t comply expressly to put Firefox out of business.
But hey, maybe some weird shit happened during the clone years that I’m not privy to.
Apple requires Developers to use AppStore with their App alongside threats to withhold their App if they don’t comply.
Just an example… and yes, I know the EU ruling but it’s still fitting.
