So you need to "offer" services, not "supply" them, and "to data subjects in the EU", not "within the EU".
So you can't just run your business from Canada with no special emphasis on EU and call it a day.
Or if you're advocating blocking European IPs, well that's exactly the "hysteria" the article argues against.
You really can, it says that it may make it apparent.
Does your use of English make it apparent that you are intent on selling to the UK? No. Italian, might I suppose. French wouldn't if you were based in Canada.
