I suspect that some people disliked Common Lisp because they worked at institutions where they were able to develop and support their own Lisps, and ANSI CL was foisted on them: "party is over, make it compatible with this honkin' document".
Is that the question?
Why not develop according to US standards?
> Was it a hedge against Lisp becoming hugely successful and helping their computer industries?
That was the plan? What went wrong?
Perhaps those issues persisted and once they were gone the culture was embedded?
