(a) was obviously dumb, but (b) had a point. We would have gotten people asking us questions. With a tiny staff we'd have had to blow off anyone who weren't paying for a support contract, which would have gotten us bad press; and given how weird intent was, we would have got questions. Part of the reason for the Amiga deal was that they'd do this for us. Well, that went well...
With hindsight Tao should have done this.

This sounds like a massive case of post hoc ergo propter hoc.
Prior to the rise of the GPL and other formal F/OSS licensing models, there was some explicitly-dedicated-to-the-public-domain software, and lots of lax enforcement of copyrights in software, and, especially prior to 1974, some doubt about the copyright status of software. Before automatic copyright in 1978, and especially before 1974, lots of software was probably not copyrighted (because it took an active step to do so and because there was doubt about whether doing so would have any legal effect.)
But I don't think open source was ever the norm for software once it was clear that copyright protection was available, and certainly not once it became automatic.
The wiki article lists quite a convoluted history, not to mention all the rebrandings. It seems like they never really focused on attracting researchers or considering any FOSS presence, which is a shame because it's now practically lost by this point.
If Hinsley answers, that'd be great.
