Expenses like paying their employees.
I will never understand how so many people in tech think that not for profit means never make a profit, or pay anyone for their time. But somehow spending money on corporate funded machinery is fine.
When a local maker space wasted thousands of dollars for a license of some cam software, but didn't want to pay a member $10 for cleaning up after everyone else (and keep them from being homeless) I had to seriously reconsider supporting a place that was so anti-people and pro corporation.
