Because it's not correct, a search in a store is supposed to result in information about the products in that store, not unrelated garbage. Garbage is a problem in the internet, much easier ways to generate/access it in more places is an big increase of the scale of the problem, hence "ruin"
The input field at the top of bing.com says "ask me anything". Would you also call that a question box, because of what it literally says inside it? Or would you call it a search box, based on our existing context of what bing.com is?
Can someone tell me specifically why correctly receiving the information you asked for is ruining the internet?
Seems like a complaint in search of a problem.
