I don’t think they’re warranted at all technically. It would just be a lot of work for Apple to now allow new browser engines with no clear benefit to Apple.

I do believe what I am saying about security is true, and it would be a non-trivial cost for Apple to have to start worrying about what happens if Chromium ships with a security bug, but at Apple scale it’s less about that cost and more about the complexity it introduces for no benefit to Apple.

To clarify I am not saying Apple’s decision is good. I think it’s very bad. I am just trying to see it from their perspective, and have to admit, it makes complete sense
