The main point is that what is legal allow is very unclear.
Hogwash. I feel the LGPL is extremely clear. It allows you to dynamically link to LGPL code without worries. Full stop.
You want to see a really clear license and short one? look at MS shared-source license. Only 1 page and written in very simple language.
At my previous job we thought about releasing the code for our product, so we gave the company's lawyers the GPL documents. They went through it for few days and their conclusion that the GPL is very complicated, sometimes contradicted and got few holes in it.
Just my $0.02 cents
