No it won't because it's still the only futute source of the Apple ecosystem. There is no rival Apple based phone with headphone jack to run to. Some people might go Android but most have iPhones because of the ecosystem, iTunes, the apps, etc... Like I said they can do pretty much what they want because there's only one iPhone.
There are literally 3 other models of iPhone that have a headphone jack.
Of course in future this will dwindle, but the SE might be a design that's around for a couple more years and the 6S will be around for another year or two as well.
We're only in a transitional period of jack removal. If jack removal is a big deal people can just wait it out with their current phones until the options mature. And the options will get better.
As for reasons Apple removed the jack I don't believe that it's for licensing money reasons. Control maybe. I also don't buy many of the excuses Apple gave exclusively. A bit of everything but the biggest one I think is just because they wanted to.
I believe They just don't want to be engineering around a port, while useful to many, there are alternatives to and will eventually be moved on from. I think likely they have done The research and that at any time there will be complaining, now is at an appropriate time and benefits their next model.
