Even the BBC is illiterate now

I just watched a video clip on the BBC website where Terry Pratchett gives his (quote) opinion’s (unquote) about assisted suicide.
What the hell is that apostrophe doing in there? He gives his opinion’s what about assisted suicide? There’s no possessive there at all. What kind of moron are they employing in the BBC these days?
Well, I’m glad to say that someone at the BBC isn’t a moron, because when I went there just a minute ago to get a link, the offending paragraph has been re-written. I’m pleased that someone is looking at the site content and correcting the bad grammar.
