I've literally never come across an open source project that was thought to have a bullet proof review process or had a lack of people making criticisms.
What they do almost universally lack is enough people making positive contributions (in time, money, or both).
This "research" falls squarely into the former category and burns resources that could have been spent on the latter.
Yet we do nothing about it? I wouldn't call that jaw-droppingly obvious, if anything, without this, I'm pretty sure that anyone would argue that it would be caught way before making it way into stable.
