Eh? Apple do want, I'm not sure what you're basing your claim off of; https://security.apple.com/blog/apple-security-bounty-upgrad... says they paid out $20 million in bug bounties in the 2.5 years before that post was made.

I meant the competition to Chrome

On iOS they are winning :-)

Apple will have to. If EU forces browser choice to iOS, there is a considerable possibility of the last bastion of browser diversity to be lost.

I know, it's kind of hilarious considering Apple, but it's chrome 70%, Safari 20% and the rest is various Chrome-based browsers (e.g. Edge) and Firefox with 3.35%.

So Apple has a choice of losing control of the most important app or improving their product, so there is no reason to switch. I am pretty sure they love control more than anything.
