I like knowing what technologies were made with to some extent. It can give me a feel for what type of bugs I might run into or what the installation process looks like.

Agreed to some extent though, once something is done, what it was written in - should be irrelevant to the end user.

To be fair though, a few weeks ago there were people on here bashing rust claiming it's like impossible to use, async didn't work, the code is unreadable, shouldn't do web dev with it, etc. Meanwhile, here's yet another example of rust being just fine. So I'm glad they shared the technology they used.
