  The paper by A. A. Shashkin et al. [cond-mat/0409100] reports measurements of
the thermodynamic magnetization of two-dimensional electrons in silicon.
Although the experimental data is very similar to that reported by us more then
two years ago, the authors arrive at an opposite conclusion regarding the spin
susceptibility "critical behavior" and spin instability in the vicinity of the
metal-insulator transition. We show that this interpretation is based on a
flawed analysis of the experimental data.
