I think you’ve correctly identified their self-interest over altruism, but you’ve misidentified the internal value of discouraging clickbait. YouTube is a treasure trove for building training datasets, and its value increases when metadata like thumbnails, descriptions, titles, and tags can be trusted.
It’s the AI gold rush; notice how this coincides with options to limit or disable third-party training but not first-party training? It coincides but is definitely not a coincidence.
For the average user you’re definitely right, but I will say for the sysadmin of headless systems, having a powerful cli editor is a godsend. While it may seem arcane and unnecessary, learning vim is easier than managing remote x or sshfs or copying files to and from a system.
I didn’t learn vim to be a contrarian; I learned it because it seemed (and still seems to be) the path of least resistance for many workflows.
