Because that's not going to add to the sense of a toxic environment at all.
Imagine a customer goes into a hardware store because they need screws to fix a wood chair back home. Once in the store they are confused by the different kinds of wood screws available so they ask an employee fo a quick tip. Said employee, who can't be bothered atm, responds with "use google." How do you think that customer is going to rate that stores customer experience?
Could they have easily googled the question from their phone? yes.
Would google have provided extensive and detailed information? yes.
Did the refusal to help and expectation to "figure it out yourself" add to a sense of community and support? No fucking way.
That's essentially what happens to new players. It doesn't matter what you
think is "better" fast and efficient. What matters is that it comes across as dismissive and feels like shit to a person just trying to reach out. The message is "don't ask for help, no one cares."
At the very least, add a "if you still have questions, /w me."
