I think what makes “free” and a vpn contradictory is that the infrastructure required to provide a reliable, public vpn is expensive to buy, run and maintain. Even a non profit or other benevolent entity needs to at least cover its costs and that means some sort of income.
And if that income is not from a monetary usage fee there really must be some other catch, be it data harvesting, user side crypto mining, ad injection, or some other, similarly shady thing. Maybe it’s donations by some rich person, but that just puts the organization under their sway indirectly.
I mean yeah, i could dig up my old computer and set it up as a vpn. That doesn’t make it helpful though, it is still in my name / using my home connection.
When i say vpn i mean a realistic alternative to existing offers, including a variety of locations and acceptable speeds, as well as the reasonable expectation that my data stays private as long as i don’t engage in wildly illegal activities.
Now for lemmy, the instances are either funded through donations such as the one i use, or are so small that the proprietors can afford to pay for running one themselves. A lemmy instance also doesn’t need to provide broadband speeds and global locations to its users.
