Yeah, it’s most likely caused by Google profiling OP and showing what it thinks OP wants to see.

Out of interest, I just entered “Reddit vs” into DuckDuckGo (which is a search engine that doesn’t profile its users, and it gets most of its search results from Bing). I got the following search suggestions:

reddit vs quora reddit vs twitter reddit vs discord reddit vs anime reddit vs facebook

I can’t believe that anime made the list but Lemmy didn’t lol
