I agree that iOS browser engine restrictions are "propping up" Safari share numbers but don't feel that allowing alternative browser engines will practically mean the end of Safari/WebKit.
How can those both be simultaneously true? iOS is propping it up but if you remove the prop the numbers won't fall?
I also think Apple should make Safari/WebKit available on other major operating systems like Android and Windows. That would help with usage levels as well.
I'd have thought a user named "webkit" would know this, but:
Webkit is already open source.
The Windows port of Webkit is maintained.
Chrome is built on a version of Webkit that Google forked so they could make it more amenable to Google's purposes.
Apple does not package and distribute a version of Safari for Windows any more, but why should they have to? And won't this then just raise the regulatory risk on Safari if it's now gaining dominance in the market?
I greatly appreciate Apple's products and ecosystem, and willingly come to Apple to enjoy that experience. I don't see why they need to pay the cost of supporting that experience on other platforms with no revenue to justify it, and I don't see why they need to undermine that ecosystem because someone covets their 20% browser share.
All of these arguments keep coming back to what Apple should do to compete-- they're competing just fine. If you want people to leave iOS, create an ecosystem with a better user experience and entice me to go. Give me a reason to want to move to a new ecosystem, don't just destroy what I love about the ecosystem I'm in and say "there's nothing left for you here, you may as well try something else."
