It's not that I have never owned wireless headphones, in fact I am literally forced against my will to own and use them and am wearing them as I type. They have some convenience, but adding a headphone jack doesn't mean not being able to use bluetooth headphones - I should just be able to use both.
Security (no practical eavesdropping)
Simplicity (just plug the damn thing in and get a hard connection; the connected device is much simpler)
Options (nothing prevents having both Bluetooth AND headphone port)
The only reason it's eliminated is it's convenient for the manufacturers and they try to sell it as if we all want it, clearly a marketing lie.
1. I already have nice earphones, I don't want to spend another $200-$250 for no reason (the going price of most wireless earbuds I've been interested in)
2. Way lower latency than bluetooth.
3. I have too many things to charge as it is. The reduced anxiety of having 1 less device to charge is worth something to me. I know USB-C to 3.5mm dongles exist, but a headphone jack is still better.
4. I oppose the idea of companies artificially taking out basic hardware features (that we've always had for 10+ years) just so they can force more disposable consumer goods to their users year after year.
Yes, and now I ended up in an idiotic situation where I have to have a pair for every device I own, because switching bluetooth connections is an unbelivable pain in the ass. No such problems with wired - you only need one pair, you plug them in, they work, end of story.
Not to mention issues like audio sync, which is just broken as hell. As an example, using top of the line headphones(sony MX4s) + a top of the line phone(Galaxy S21), audio isn't in sync with anything other than youtube. Playing games? Enjoy hearing your shots 1s after you fire them. And using them with windows? Now everything is slightly out of sync, because windows is a flaming pile of garbage when it comes to bluetooth audio.

Eavesdropping on either the output of the headphones or the audio data before it leaves the computer/phone is the same for wired vs Bluetooth. The latter seems to be the mode used in the (pretty coo) hack you posted - it's software attacking the Realtek chip, which must be driven by the wire, so exploiting the quasi-equivalence/reversability of speakers/microphones and the back signal from the speaker diaphragms.
This still requires access to get malware onto the device itself, and I'm more considering 'drive-by' or remote attacks in my comment.
To do this against a ~1m wire with millivolt signals without putting a clamp around the wire seems pretty tough in contrast to cracking a signal that is explicitly broadcast with not great security. Not only that, while eavesdropping the signals on the headphone wires will yield only a conversation in the room, which can be much more easily gathered directly, cracking a Bluetooth 2-way comms channel will yield much greater access to the device.
For most of us, neither is a concern, but it certainly is for people who do have real security needs, e.g., I've read that the current VPOTUS specifically uses wired headphones for this reason. Many people who also work with Classified information, Controlled Unclassified Information (CUI), or just with business security issues have the same need. Failing to produce a device with this capability is a failure to address a key and leading market.
