No, as a customer, I want CHOICE. People act as if having a headphone jack vs using bluetooth headphones are completely mutually exclusive things. I sometimes find downright aggression towards people who still want to keep a headphone jack. A laptop is a general computing device - maybe I'll want to plug in my fully working wired headphones, maybe I'll want to use bluetooth ones. Who knows. But I hate it when companies take this choice away from me, because "progress" or some other nonsense. And then you go online and people say that you must be weird for wanting to keep the jack around - why? What's bothering you so much about having an extra port that you can but don't have to use?
From a strictly cost/business perspective it's brilliant. Remove hardware you have to pay for embedded in your device and sell people an adapter at an increased price.
