Sure: "Should Google be involved in censoring extremist content?". There's a moral question on exactly this issue. And the answer doesn't depend on whether it's possible for Google to do it or not.

What you guys and your downvotes are doing is trying to avoid making an argument on the moral issue directly (which is hard) and just taking potshots at Google for their technical failure as if it also constitutes a moral failure. And that's not fair.

If they shouldn't be doing this they shouldn't be doing this. Make that argument.
