These dongles that came with phones were also usually very thin. It also sticks out and made of plastic.

I agree that many of the ones that used to come bundled with phones (they don’t even do that now) weren’t great, though you can buy some pretty good third party ones now with sturdy ends and better quality, flexible cabling in-between. They don’t have to be expensive either - I bought mine (CX-Pro CX31993) for AU$10 and it is durable and sounds good.

But yeah, I share your frustrations overall. It was an unnecessary removal of a useful feature to increase profits on already expensive devices. It’s the same with the removal of the SD card slot to sell internal/cloud storage, though thankfully that has remained on many of the less expensive phones. I am definitely not trying to defend the manufacturers here, only point out that there are solutions for those like myself who want to continue using their wired headphones with newer phones.
