> I wonder why apple is so hell bent on enforcing Safari/Webkit as the browser engine?

security. browsers are famous for escaping their sandbox.

this is from November 2023: https://www.theverge.com/2023/11/30/23982296/google-chrome-b...

Realistically support for more than one browser engine is going to increase security in aggregate since it would implicitly decrease the impact of a vulnerability. This has a compounding effect where a zero day for Safari would become less valuable on the black market and therefore become less incentivized to a degree.

To give an example: A single Safari engine bug could compromise all iPhones, but if the market share was say 50/50 with Chrome, then the impact of a security vulnerability would now be halved.

Historically, that's also been a huge vector of attack in iOS too. From the old and famous slide to jailbreak to more recent Pegasus.
