Well you shouldn't cite Wikipedia in your paper for the same reason you shouldn't cite LLMs, they're tertiary sources. You shouldn't cite a paper book encyclopedia either. It has nothing to do with digital literacy so I'm sorry if that's what was taught to you.

You should look to an encyclopedia for information about all manner of topics. Someone did the work of organizing, verifying, and cross-referencing the information from disparate sources for you. It doesn't mean the information is untrustworthy, if that were true the paper you wrote in class would be untrustworthy which is absurd, no?
