Because there is no twitter anymore.

Because there is no guarantee that: A) Twitter will exist within a year B) Musk won't takeover or delete your account C) Twitter has been experiencing plenty of random downtime due "production experiments"/cost saving.

I also don't think it is intended to be a replacement, looks more like for help and general outreach; I mistakenly described it as 'swapped out' which I think has created some confusion about using youtube as a bug tracker.

You can see in the git diff, that they replaced the "Join us on Twitter" button with "Join us on youtube". They are removing the feedback option completely, but replaced some other mentions of twitter and this one was replaced by youtube but has nothing to do with the feedback option.

It'd be hilarious if the "report to YouTube" does a screen-recording of how to reproduce the bug/what it looks like; hilarious because it would mean the VSCode team put in a video renderer in the thing.

> YouTube? To report issues?

Screen recordings are a basic issue reporting technique, which objectively documents not only the issue but how to reproduce it.

Email tends to have a low file size limit, and YouTube is designed explicitly to share video.
