To be fair, in that specific case it is almost certainly not YouTube directly censoring the phrase. They aren’t known to do any kind of editing like that on uploaded videos.

What is happening is the person that uploaded that video censored themselves…because YouTube’s policy around monetization. They’ll demonetize videos with certain no-no words. Part of that is YouTube and part of that is advertisers demanding their ads not be placed on content that they find objectionable.

Indirectly, YouTube and advertisers are censoring our content. A lot of it is also TikTok, which will ban you for no-no words. This seeps over into YouTube where something that might be fine on YouTube but is banned on TikTok gets censored anyway in case it gets clipped for TikTok.

Genuinely the power TikTok and it’s advertisers have over how we communicate is pretty scary. Imagine how often you hear “unalive” instead of “suicide” these days. “Pdf” (or others) instead of “pedophile.” The list goes on.
