I'm related to a formerly famous youtuber
Did you use your relation as a way to get famous as well?
No, I didn't.
Nepotism robs a lot of hard-working, talented people from jobs. It's great that you decided not to guilt or abuse your relation with a famous relative in order to bypass others.
It's okay if I were able to take advantage of my relation and get a big head start in the vlogging business. Everyone does it.
Just because everyone does it, does not make it the right thing to do. The actions you took earlier were good, don't take advantage of your relation.
