Absolutely but quality also will be reduced significantly over time. Working for the money certainly has huge drawback. He just does it because he want to and inspired to do something instead of he have to which I greatly repect about shirami.
Nah, they just put out stuff that takes A LOT of time and aren't doing it for money, so it takes lots of time between releases. Also, both the length and quality of vids has increased so it's going to take even more time between drops. I know other artists get work done faster but all of them have income streams connected to the content.
