Ok probably there's some miscommunication here. GitHub has always been a progressive website (not progressive web app, just a website with progressive enhancement), it just was a mish mosh of JS with jQuery, they documented over the years the evolution of the web app and now they decided to remove jQuery. That's it.
Yeah, doesn't seem like the right choice to me.
Obviously, I am wrong and they are right, so I was curious about the rationale.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
