I think some harsh language was used (probably because of frustration), but I think they didn't mean to imply outright _malice_.
More like "incompetence" (eg poor people skills, planning skills, and often lack of technical understanding), followed by shallow human nature which gives in to survival instinct, which generally leads the PM to "blaming developers", so they they don't themselves get in trouble (and a lot of people have problems owning mistakes in general, but that's enough misanthropy for one post).
Also, they don't really _blame_ the developers by point a finger at them and shouting "he did it" like some childish display. They try to soften the blow (humans usually try to be decent; we just can't agree what decent is always) by adding an adversary into the story (like the technical debt, or hidden complexity).
Edit: Forgot to address this, but talking to a PM can often backfire, because you need exceptional interpersonal skills to have difficult those kinds of conversations with a PM. And if they're insecure and take it the wrong anyway, they can make you even more miserable.
