Johan,
I think the source of the problem stems from some of the practicioners of 'modern jujutsu' who try and claim koryu status. There is nothing wrong with their style per se, but their attitude and self promotion are the point of contention.
That said there are some styles that I have seen that are terrible and are purely cashing in on the grappling boom at present and the jujutsu boom of some years ago.
Here's an analogy that I like:
You have a can of paint (in this case jujutsu) it is good paint, the perfect color. Over a period of time conditions vary, you decide to experiment and mix little bits of other colors into your can subtly changing the color. As you mature you decide that your paint needs to be passed on, you choose someone and give him the paint can. He too experiments and adds different colors.
Over a period of time the can of paint passes through many hands and many other colors get added, the current color does not match the original color much any more, it's still good paint but it's not the same.
Someone comes along who never saw the original paint, he only has heard stories. Today people value the old things more, so he decides that he wants to return to the old paint.
It is impossible to remove the colors that have been mixed in over the years, they now form part of the paint, you can try to add larger quantities of various colours to try and override the effects of the added colors. You may get something that resembles the original color. But it is still not the original paint.
This is what some people have tried to do, they are taking the new paint, be it judo, aikido, karate or what-ever and are trying to add other bits and arrive back at the original jujutsu. You cannot reverse engineer like that. There is nothing wrong with their system, but it is not jujutsu.
If they were to acknowledge the process, then that is fine. Many people do do this, John Bluming is one example that springs to mind. But many try to hide behind names and traditions that are not valid, this is wrong.
Most 'westernised jujutsu' systems are perfectly good martial arts as long as no one claims that they are traditional jujutsu. Some however are not, and unfortunately it is often those that recieve the coverage. They bring any bad feeling on themselves and lower the standard of fighting as a whole.
