I think the best outcome would be if the person posting their video genuinely put effort into making the video out of their own personal interest, as well as wanting to support the developer. In that regard, I would be happy to see someone not only put effort into something they love to do, but also wanted to support me.
Sometimes however, it feels like people are posting it just with the intent of getting views on their video. Maybe they still choose to showcase your game because they were interested, maybe they just saw it as a good strategy.
I think that still benefits both parties, so minding it personally would not make too much sense. But it still seems a bit on the nose. Sometimes I can understand that approach, as every person may have a different reason or thinking process, sometimes it does feel a bit disappointing.
