I’d like to go here.
I had no idea, but there’s a little adapter you can buy for Fujifilm cameras that lets you attach Canon EF lenses to the body and retain all auto-focus features. From what I’ve seen, the adapter works near flawlessly with just about all EF lenses and the focus seems fast.
These nifty-fifty lenses typically don't break or malfunction even though they are on the cheaper end of the Canon lens spectrum and they have a proven track record of being incredibly reliable. So I suppose when Canon saw enough of these fake lenses to warrant issuing a press release about them, they figured they'd remind people that you basically get what you pay for. In this case, a fake lens that doesn't work for long.
