This is actually still working! Trying on one of the top posts right now, if you change

https://www.reddit.com/r/funny/comments/1ezq3po/asked_for_my...

to

https://www.reddit.com/r/funny/comments/1ezq3po/asked_for_my...

you get all comments as json, with no need for authentication. So it's probably trivial to develop a client that would use this and have a nice ui and bypass any and all ads. Interesting.

AFAIK, you don't actually get all comments, and it's impossible to enumerate all comments to a post via that method. Give it a try to enumerate based on the data that gets returned, and you'll end up with a way smaller number than the reddit UI shows on the website.

It still supports JSONP [1] too, a little React app I haven't touched for 9 years which used it [2] is still chugging along

And now this is commented it will be changed. :(

Maybe not. The incident described by the OP happened in Aug. 2023; it has worked since then, despite Reddit being very much aware of it. It's possible there is something in Reddit's architecture that would make it very costly to change...
