Sure, if it’s just a bare link in the comments I understand, but as a post with the original video title and usually an autogenerated thumbnail, I don’t see a problem.
The YT descriptions are not shown in the list of videos and rarely contain a summary of the video.
I really don’t get why people get so upset about that. We don’t get summaries on Youtube either but still watch the videos.
There’s just something off-putting about a text based forum getting video content.
We go to youtube to watch videos. We go to lemmy comments to read text.
Youtube videos DO have descriptions, though?
