It's because Lemmy can't fetch YouTube thumbnails. I swear it used to fetch thumbnail and title automatically before, hmm
It's because YouTube puts a bunch of JavaScript at the start of the file (1MiB) before the opengraph tags and Lemmy only fetches the first 512 KiB (a fix was merged a couple days ago).
If you don't put a whopping 1MB of JavaScript in your website, you're doing web development wrong.

I can fetch the damn thumbnail just fine. I have to do it on every YT post I submit.
Reddit can fetch thumbnails from hundreds of websites, all of them different, including a bunch of porn sites. Pretty sure they have to code each site to map out the right URL and tags to parse.
I know Lemmy is OSS, but I really wish it wasn't so slow on the uptake with these things.
I can testify to this. I was there. I was there when Lemmy so valiantly fetched ye old YouTube thumbnails.
