I think the hostility is is from the books failure to talk about the movement in polarised terms. It is weak on the old rhetoric of class struggle and against US hegemonism. Truth is described in an associational rather than an oppositional way.
And it was written at the time of the rise in street protests against globalisation, largely non-violent, and before 9-11 changed the whole climate. Therefore it had the feeling of the Prague spring, and brought to mind their memorable allusion in the final words to the "incredible lightness of being communist".
To claim that they are pre-marxist communists is a nibble conceit, seductive for some, offensive for others.
Can the world really be changed by such narcissistic frivolity?
I think these are some of the roots of the hostility.
What counteracts all that in my opinion is the scrupulously careful way they re-examine Lenin's arguments over ultra-imperialism, and argue that the ultra-imperialist tendencies have become stronger, and must be addressed.
