This is a completely extemporaneous answer, but I would guess
that Heidegger's dislike of Marx (wgich is not unequivocal, as witness
the _Letter on Humanism_, where he gives a high assessment of the value
of Marx's account of history) is two fold. First of all, Marx is
a reductive materialist who reduces all metaphysical systems to
accretions upon and justifications of particular socioeconomic structures.
Second, Marxism is, to a large extent at least, a Utopian humanism,
which turns the welfare of human beings into the summum bonum of
revolutionary activity.
