> people said that scraping/calling an API without service owners permission is not allowed I think it is legal, the API is public data and accessing it should be protected by the First Amendment as far as I know. Otherwise scrapping in general would not be allowed and search engines couldn't just crawl sites and list them as they'd need the permission of every site operator they list. I don't see why APIs would be treated any different, and in Invidious' case they are actually scrapping the HTML page and not using the Android YouTube API. So it's a slightly different case but I do think that using that Android YouTube API should be OK as well, it's all public anyway.
