One example, Ocasio-Cortez asked: Can a politician lie about Election Day on a Facebook ad?
The answer is clearly yes. It isn't complicated.
Or this one: Does Facebook see a problem with its lack of fact-checking capabilities?
How can the answer to this be anything except yes?
Imagine that Facebook is required by law to check every fact in every advert that is on their platform. Is that even possible? Would they have the resources to hire unbiased, critical-thinking people who are capable of doing htat? How expensive is that? Would they just rely on the cheaper option - algorithms.
A friend of mine got banned from Facebook for a month for sharing a meme, posted by somebody else, that had a swastika in it. The meme was of the sort "Nazis were horrible idiots". He appealed the ban, on the grounds that the original post was not taken down (he just shared it) and that this had nothing to do with nazi propaganda. It was, in fact, the opposite. An actual human being looked at that appeal and still confirmed the ban.
What makes you think the process will be any more efficient and rational with political advertising? Relying on companies to police content is absurd in every respect, from freedom of speech rights to just plain capability. There's an entire court system built up with the sole purpose of determining truth and even that isn't 100% accurate. Trust the same responsibility on a corporation?
If the person doesn't answer the question, go ahead & berate them. Just don't expect a complicated question to be answered with a simple yes/no.
Likewise it's terrible to judge a politician based on their yes/no voting record without understanding why they voted for/against something.
