People really are so quick to point out LLM usage as some form of virtue-signalling.
It's fairly obvious that an LLM has been used to design the site, but it does the job and the site isn't the focus of the product.
The idea that every open source project has to be a product backed by garish marketing material is something that only comes from the entrepreneur-bro types. It's right to call it out.
If it were an overly elaborate human creation I'd agree that criticism was unnecessary and perhaps even insensitive.
It's not virtue signalling but it shows that if the author of said software (if there's one) didn't bother to spend time writing things on the website, there's a correlation that they wouldn't bother spending time writing code either.
And that's what I see first thing on the repo. Lots of LLM-style writing in the README, which makes me think if this is a vibecoded app, which looks like it.
