Looks to me that it is precisely academic drama (e.g. the pursuit of citations & credit taking at all costs) that leads to meaningless work

People who post half-baked papers with misleading claims on arxiv to by-pass peer review & be "first" do so because of poor incentives

That's definitely part of it. But it could also be they just don't know any better & were in fact proud of it.

Yoav may not have been diplomatic, but his concern seems to be that leading to echo chamber of poor research that drowns out better work.

Peer review is not the solution. PR provides very little value (sometimes negative) and is part of the system that encourages flag planting

That's a strong statement. I agree there are many problems with PR, but it provides quite a bit of value in filtering/improving bad work.

In theory maybe; in practice PR is broken. Consider that the inexperienced people you see on arxiv are the same who will review your paper

But there's less harm done in posting a half-baked preprint than in reviewing (either positively or negatively) work you don't understand
