Just as a foreign newspaper can be the best way to find out the actually important things going on in your country/culture, maybe a foreign algorithm (or rather algorithm-moderation complex - I suspect facebook recommendations have a lot more manual tuning than anyone would admit) will be better at recommending in a neutral way. (TikTok of course has blatant biases on particular issues - but they're issues that are less relevant to most westerners than the things which Facebook/YouTube recommendation is biased about).
