  In The factorization of the Giry monad (arXiv:1707.00488v2) the author
considers two $\sigma$-algebras on convex spaces of functions to the unit
interval. One of them is generated by the Boolean subobjects and the other is
the $\sigma$-algebra induced by the evaluation maps. The author asserts that,
under the assumptions given in the paper, the two $\sigma$-algebras coincide.
We give examples contradicting this statement.
