Regardless of what the official pronunciation is, people say OH-ESS-ECKS all of the time. That’s a fact, just as people say Mizzuruh and Fujickle despite different pronunciations promulgated by authoritative sources.
And some people pronounce nuclear, "nukyuler," including a particular past President who shall go W'less. That doesn't make it correct.
Ignorance is it's own punishment. Thank God it's curable.
