"Company allowing the spread of nasty election lies" quite literally describes what any media company is doing when they give air time to pretty much any running candidate.

False equivalence

Sort of. It's how you spread the lies. How they are delimited.

One halfway responsible way: "here is a paid announcement from someone that doesn't necessarily reflect our views: ${LIES}".

On the other end of the spectrum are sneaky, dark patterns and whatnot.
