The NewPipe project recently had a few debates on advertising, its ethics and how Team NewPipe decides whether or not a certain form of advertising is acceptable. In this article, we present our position on advertising in general, show the difference between ethical and unethical advertising, and explain why we do not intend to support technologies like SponsorBlock.
Apparently Youtube allows authors to distribute CC-BY licensed videos on their platform. The lack of Share Alike clause is unfortunate but I suppose it’s better than nothing.
