Because Google put Quora answers at the top of their search results when people search for a question they see the answer from Quora. Which is stupid because most answers on Quora aren't even correct lol. Idk why Google wants to promote that site, if they own it or they want to buy it and incorporate it into Google at some point. I think the site is awful and it should be shut down because it's just a propaganda site. You do not see Quora from any other search engine for example duckduckgo. But you see it in Google.
