Soon it will be possible to run browsers on iOS that are not using Webkit. That is a big deal.
Apple is trying to frame it as dangerous.
Sadly it will only possible to run those browsers in the EU and browser makers need then to provide different browsers in the EU and outside. This requires more resources, which makes it harder for smaller developers.
Apple also wants developers to pay for the right to provide downloads from other app stores, which now become possible in the EU, and directly.
IMHO every user on an iPhone, as well as on any other device, should be allowed to run the browser of their choice!
