Yes, it happens quite often recently. I think, their approach is "dominate and tolerate" in a controllable way, so they know quite a bit about who is actually using NewPipe, yt-dlp, etc. and they tolerate it in order to have a kind of leverage to preserve their monopoly. Then if number of out-of-official-app views becomes like above certain point, they aggressively block with "bot detected" message.
