In general, having Trump speaking on something in 2014 doesn't mean he'd not flip on it in 2018, but Trump has showed very definite desire for reducing regulations, so without an explicit statement I'd say it's unlikely he'd support Net Neutrality. He also doesn't have much tactical reason to - NN is the cause of major content companies, like FAANG, and those are no Trump's friends, and neither they are friends of his base. So Trump has no reason to try and make nice with them.
