The big issue with removing the headphones jack is just that it’s now impossible to use wired headphones while charging the phone.
For a lot of people that doesn’t matter but for some of us that’s a big deal. If they added a second USB-C port that would fix the issue.
But saying the 3.5 jack is legacy technology is also kinda wrong. A USB headset is not inherently better. You have to compare the digital audio converter that’s used. While USB headphones use their own dac, the jack uses the dac of the phone. So a cheap phone with high quality USB headphones will be better but a high quality phone with cheap USB headphones would be worse than using the jack.
Which even means jacks would be more sustainable because you only need one dac per phone rather than one per headphone.
And any form of wireless headphones are just inferior to wired connections.
YouTube doesn’t have a say in this, it’s up to the copyright holder of each individual song. YouTube just detects if a song is copyrighted or not then gives the owner the option what to do. The three common ones are
So whoever holds the rights to Phil Collins song is the one responsible for your video being disabled. While whoever holds the rights to the song Joe Schmo decided to go with option 2 or 3.
This process has mostly been automated. So it feels like YouTube is doing it but they are just following the orders of the copyright holder.
The system is a bit overzealous in some cases and even fair use gets flagged.That’s on YouTube. But to be fair, it’s very hard to have an automated system detect the difference between fair use and not. YouTube should just implement a better way to dispute false copyright claims.
