>Safari is holding back the mobile web the exact same way IE held back the desktop web for the exact same reason: native apps.

That's a classic tinfoil theory, but with absolutely no substance.

First, Apple sells hardware, first and foremost, not apps (it's the inverse with Microsoft). Their app store profits are negligible compared to all else.

Second, Apple has consistently made the best mobile web browser for many years -- Android had the horrible crippled Android Browser which was not even competing, before Chrome became competitive there.

That's not what you do when you want to cripple mobile apps -- which few users care about anyway, the money (for developers) and the convenience (for users) are at native apps.

Do you see "mobile apps" thriving in Android or MS Phone compared to native apps? Because I do not.

>Lol? I know very few (none?) web developers who uses Safari as their primary target browser. ES6 support or not.

What Lol? Safari's engine is what Chrome has been based on, and for most of its life it has been one and the same codebase.

Developers just don't prefer Safari's developer tools compared to Chrome's -- and of course Chrome is more popular (and cross platform), so it makes sense to use what most users use. Back in the day all developers used FF and its dev tools too, for similar reasons.

What does "Primary target browser" even mean? Many (me included) prefer Chrome as a dev browser because the dev tools are better and many extensions are only available for chrome (react dev tools etc.). But at the end of the day, you need to support Safari (which usually isn't a problem).

Off topic tip: I've had success with the Safari dev tools on some issues that I couldn't debug on chrome. Sometimes it's worth trying both.
