I could be wrong but after spending 2 minutes finding out about them, I think that sort of thing is their actual business, not just a small flaw in a blog post?
I guess their reasoning is that since they create one UI "idea" on their main product, it should therefore be used absolutely everywhere. Clearly people want to open popups and click one thing on the popup again when they actually just want to click the link.
I guess so. I revisited it and realized that bubble had a link in it. That's ridiculous, of course. I thought it was user content and ignored it entirely.
