Just had a butchers at the Full Fact website and their latest article is about a former nanotechnology firm that started up back in 1996 but finally ceased trading in 2019 (ironically before the start of the current pandemic) whose name was Omicron (after the Greek letter of that name) and there has already been many myths and conspiracy theories circulating online about it, despite the name of said firm being purely coincidental and having nothing to do with Covid at all!
Just demonstrates how much the world is full of mugs who are susceptible to being fooled by such things, especially completely unrelated stuff of a same name!
