"common practice across the entire web. Once there they are simply saying what they believe. If you disagree, go elsewhere"
So, you would be ok with a search for, say, a history of socialism, you click on a link that says "a history of socialism" but ends up taking you to a pro-fascist website? (this is a hypothetical example, just in case you don't get it)
Or searching for help with the latest MS OS takes you to an Apple page despite it being advertised as a Microsoft one?
It's exactly the same thing.
