Now that Apple is forcing app developers to use Sign in with Apple -- and developers will have to also allow it on their websites so you can access your account there -- Apple will be able to use the Sign in with Apple javascript they serve to track you around the web just like Facebook and Google do, even if you don't use any Apple products.

While this is true, it is obvious how the other names he listed would benefit from such tracking. It is not clear to me why Apple would do this, as it runs opposite of their product marketing, and their business model does not obviously benefit from tracking the way the others do.

I didn't say they would or should. Just that they will be able to.
