No, the actual good move would have been for him to pay someone, or a company, a percentage of the revenue to make high quality videos for him, at the very begining.
The fact that he didn't do this, in the first place, means that he left hundreds of thousands of dollars on the table, which he could have captured if he had put a bit of effort into paying someone to make his youtube channel in the first place.
Monetizing isn't the "fun" part of streaming though.
You are assuming that this is some large amount of money for a streamer. It is not.
It is possible to outsource your entire YouTube presence to a company, that will merely take a cut of the profits. So there would be no risk, if you give a company a percentage of the revenue.
E.g: nintendo killed an incredible fan made metroid game. It seems so short sighted.
