All good points, and I'm not trying to bash John (although it may seem that way sometimes). John always says that his goal was mainly to get stuff out there - to provide some kind of access to as many people as possible (as I mentioned, some of the material that he's translated isn't even available in Japanese anymore).
To that end, it had to be presented in a form that would be relatively digestible in small doses. If you presented, for example, a single Doka in the way that it ought to be presented, with a full page of explanation and dissection (and I've done a couple myself) - it may well be that only a very tiny audience would actually end up reading the thing.
You make some good points and I, too, am not trying to bash John Stevens, as you put it. However, there is a great risk that in presenting someone like Morihei Ueshiba to 'as many people as possible', you end up with 'Ueshiba-lite' and I think the aikido world suffers too much from the consequences of this already.
