The thing is, OL is free. Hence, they have zero obligation to do anything. There is no contract between OL and visitors. Were it a paid service, it would be a different story.
I've enjoyed PZ during its time and now OL as well and I fully understand why reviews have slowed down and I fully accept it, regardless of the reasons, eventhough I wish it would be the way it was back then. I'd much rather have a slow paced OL than any other commercial or free (but with low credibility) sites out there.

Thing is, just because "it is free" does not mean one can't have issues with something in whatever way. 
I don't understand Markus' reasons, as they are not known as far as I know. I do not have to know either. I also understand that people criticise the lack of Nikon related lens reviews for instance. No, you can't DEMAND reviews, that is obvious, nor should one sue OL over that. You can, however, complain about or point out the lack of them.

I prefer no car over being in one that explodes. Does that mean I can't mention/complain about/point out the lack of a car? Your last point is a silly one, is what that silly example of mine is meant to convey.
