That quote might be misleading:
"Volunteer work is an increasingly large, yet ill-understood sector of the economy. We show that monetary rewards undermine the intrinsic motivation of volunteers."

The earlier sentence make it clear they are talking about monetary rewards specifically, not any kind of reward. A t-shirt might notionally have a $ value, but it is not a monetary reward. Plus, the nature of a branded t-shirt has an obvious team-participation / prestige value.
If rewards demotivate people, we should also avoid positive recognition, or praise, which is a form of reward; of course this is unintuitive, so I assume monetary rewards are a special case.
It is tricky.
We all hear the stories of the person who saves a company a million dollars, and then gets giving a coffee cup (or an attaboy) for recognition.
It gets even trickier when the giver and the receiver have wildly different incomes.
Generally I find money to be a terrible proxy for what I actually value, but other options are worse proxies!
