It does happen fairly frequently to large YouTubers, we just don't hear it because the large channels have connections to real humans at Google who can resolve the situation quietly. BitWit is a channel with over 2 million subscribers who was copyright striked by The Verge after uploading a parody/reaction video to their PC Build video. I know this isn't exactly the same since those were DMCA complaints filed by The Verge legal team while TFA is about automatic ContentID claims made by Google itself. You mentioned Linus Tech Tips; interestingly, I know of one recent ContentID claim affecting them, but it was in reverse: someone else made a video about LTT and Google flagged it automatically. Linus said at the time that there is honestly not much they can do when that happens. Imagine feeling so powerless about your own content that Google insists is being infringed.
