OpenCL is not ATI's technology. When i spot such an inacurracy in an article, i stop reading it, since i have suddenly no more reason to believe that the rest of it isn't just as inacurate
If you're able to verify a small number of "facts" presented in the article, and a big proportion of those are false, the probability the entire article is bull went from 'unknown' to 'very high', relative to your personal knowledge.
Eventually you could be wrong, but there is enough sources of information on the internet to allow me to choose not to read those i think are bogus.
Even worse, the mistake i pointed out is a very simple one. It's almost impossible to think, from the information you find on the web that openCL is ATI's equivalent to nvidia's proprietary CUDA technology. The mistake serves the article well though, by antagonizing the two technologies, and making the whole thing more sensational than it needs be. So this isn't a simple "irrelevant" mistake like you said. It's bad journalism, plain and pure.
