Invidious is just an alternative frontend, much like Piped. It’s against YouTube’s ToS but that does not need to concern you (in most jurisdictions, you can’t get prosecuted for using or recommending a website that breaches a civil contract). The videos are still being pulled from YouTube’s servers so only those YouTube will serve are available (albeit under conditions YT would not approve of, such as without ads, with free broader playback speed options etc.). However, the server’s location can be used to bypass region-locked YouTube videos, which might be considered priracy.
Also, there are client-side alternative frontends like NewPipe, Revanced (modified official proprietary Android app) and Grayjay (with optional features like Subscription Exchange and Polycentric integration relying on FUTO servers).

















I wonder what that means /s
