YT as a platform is a mess and sadly most of people on there only cares about clicks and making money in a scummy way - so its easy to put "baddie" sticker on everybody that makes YT materials.
The thing is - DCS is not a money maker on YT, so thats one.
Our niche hobby can only benefit from more people presenting the content of DCS - thats two.
If somebody, especially our fellow flight simmer makes entertaining and informative videos on YT, likes it and (if VERY lucky) makes some pennies of it - I honestly cant see any issue, that's three.
If they should or not (and who) receive preview of the DCS products - no idea, this is for ED to decide. I can only speak for myself here - personally don't see the big issue.
