Worth noting that Apple doesn't just cripple iOS Safari, it cripples all iOS browsers because it also forces them to use WebKit, the crippled browser engine underneath Safari.
It would be fine if they just made Safari bad, that's their choice. But they don't stop there: they make the entire web bad on iOS purposely to promote the native apps they can tax.
You realise that's what Apple has been doing for the past 15 years? Force users to do what's best for them, and only them? Anti-competitive practices do not serve customers, they increase prices and prevent innovation.
How do you explain that all other OSes, including Apple's own macOS, manage to allow other browser engines?
Do you think the iOS team is that incompetent?
