I like how that article claims PR firms don't lie and then proceeds to discuss how their best PR campaign was effectively a lie.
> We estimated, based on some fairly informal math, that there were about 5000 stores on the Web. We got one paper to print this number, which seemed neutral enough. But once this "fact" was out there in print, we could quote it to other publications, and claim that with 1000 users we had 20% of the online store market.
It sounds like they did good-faith estimate that there were 5000 stores out there and really believed they had 20% of the market? I wouldn't call that a lie as such.
