Yes. If someone other than you paid for the direct operating expenses,
that's a clear violation of the pro-rata cost sharing provision in 61.113.
As far as the FAA is concerned, not being charged is the same as being
charged and being compensated at 100%.

That's assuming the owner of the airplane paid for those expenses. It
becomes even MORE problematic for the private pilot flying for nothing if
some third party pays those expenses, as is being suggested here.
