People just don't seem to grasp the concept at all: a lot ask why we run the mesh network and how we finance it - if you explain them it's run for free and there is no profit motive they think you are crazy. It's also surprisingly popular to assume for free = useless - some declined running a node due to this.
On the other hand working for free in uni context is basically self-slaverly - lot's of work, lot's of stuff breaks constantly if you run your typical FOSS stuff and nobody is seeing the work and most don't care or at worst you are blamed and new people advocating their favorite commercial cloud services.
It's still fun and I can learn a lot, run some infrastructure for free where I can test stuff but you really need to be careful to not foul yourself and depending on the org you are in to not just work for free.
The saddest thing about the university thing is: If you advocate to pay that position a lot of - I'm just blunt here: "rich kids" advocate against it because you are at uni anyway and they tell you it's an honour to do this... however if they don't get refund for partly insane travel costs for their university pet project hell breaks loose...
