Bitcoin is the only Blockchain implementation that has gained any kind of traction, and that is due to the incentive model working out. People just don't like it because it challenges their economic worldview.
Would you mind pointing to the relevant sections?
I wasn't able find criticism about Proof-of-Stake there. Instead, the beginning describes the problems with Proof-of-Work (which Proof-of-Stake tries to address). The large middle part describes some systems which mix both PoW and PoS.

Not sure how this is relevant to the discussion about Bitcoin hypes and Ethereum.
In particular, I don't see why the people who implemented Ethereum shouldn't like Bitcoin. And even if they do dislike Bitcoin, I'm pretty sure this is not because it challenges their economic worldview, as Ethereum challenges the common economic worldview even more.
It is a good, generalized overview of the faults in proof-of-stake consensus systems.
"One problem is usually called the "nothing at stake" problem, where (in the case of a consensus failure) block-generators have nothing to lose by voting for multiple blockchain-histories, which prevents the consensus from ever resolving"
