I really miss the discussions of manufacturing improvements and design revisions that Ian Mc-whatever has in his older videos. Even if he's uploading elsewhere he's tailoring he newer stuff to the YT rules so he's not discussing manufacturing as much. Which is stupid when you consider that so much of the stuff he deals with is historical curiosities from over a century ago and incremental manufacturing innovations of the industrial revolution was what spurred the creation of a lot of the stuff he deals with.
They don't let him talk about manufacturing? That makes no sense. Though I guess he's just reverse engineering the rules so it could be some random thing he's mentioned a few times when discussing manufacturing that YouTube takes offence to.
Well he probably could and defend it since it's historical education but Youtube's enforcement is so sporadic and heavy handed and the appeals process is so broken it's not worth the risk.
