Why do people say Rust is not good for web dev?

I keep seeing posts here on this subreddit that Go is the way to go for web dev, that Rust it too complicated for that?
What am I missing? Why?

I went from only knowing to write a hello world in Rust to having four REST APIs in production in no time. And it’s very fun as well. I hate it when I have to go back to JS/TS where I don’t have Option/Result/match/etc.
I’ve been using Poem and the suport for OpenAPI is awesome as well.

Not to mention that when deployed it barely uses 8-9mb ram on the server.

What am I missing? Why do people are against using Rust for web dev?
Can all this negativity towards it lead to people putting less effort in web frameworks and not maintaining them anymore or loose interest in developing new ones?
