A family member works for a company that writes and publishes a mandatory handbook for GPs in Australia. One day the WHO found them and wholesale copied large chunks of their content verbatim into their online resources without asking or informing. They only found out because THEY went looking on the WHO website for the latest information on something. At that point I started wondering just how much of big companies' work and content is just plagiarism and gratuitous theft from reputable but less visible or popular sources (also highly dependent on country, language, etc). And that was before I discovered hbomberguy on YouTube.
