Why do you think “most” bought bluetooth earbuds in the first place? What’s the source for your data regarding how many people want the jack back? Also, not sure where you live but in the EU it’s very common to see people wearing wired earbuds/headphones.

Again, you’re defending corporations taking away options from consumers while also (presumably) being a consumer yourself. Adding the jack would not make the phones more expensive and would also not take away any of the features you want. Why would anyone in their right mind be against this? What a joke.
