I don't mean so say that criticisms aren't valid; just that perfect is frustratingly often the enemy of better.
For example, the status quo can be justified by "it seems obvious that" rather than being evidence-based. In practice, single or double blind is very often not actually blind [1], in which case it's hard to argue that it would be any different than transparency. Likewise, a new solution "creates all kinds of conflicts of interests and biases", without even considering whether the existing CoIs and biases are any better. Likewise, if people who game the system today have a low reputation, why would the same not hold true in a new system? Likewise, does anonymous peer review actually improve the quality of the reviews (e.g. [2])?
It's good not to blindly embrace something new, but I think it's important to withold judgement too, and see how it plays out in practice, and to make an effort to compensate for the prejudice people typically have towards the status quo.
And yes, absolutely agreed that much more needs to be addressed to improve science. But I also very much take issue with the idea that peer review is fine as-is.
