One thing I heard which may (or may not) be enlightening:
While it is true that Tomiki did add competition to aikido, it may not be that he "wanted" to do that. I heard one bit of history (historical fiction?) that stated that Tomiki was required by Waseda University to have competitions in his aikido program if they were going to have it on-campus, and take advantage of university resources.
I can't remember where I heard/read this, but if it does contain a kernel of truth, it could explain the basis for a lot of apparently anti-aikido sort of philosophical stuff which came from Tomiki during that time frame.
Anyone else have any more on this point, either way?
I've read some passionate defences of competition in Aikido by Tomiki. More importantly, there is an Aikikai club on campus, and it has been there since 1960 - long before Tomiki went competitive.
