That's not what the article suggests. The article suggests an ad on a page with an ubiquiti url.
While it may be the same software under the hood, I agree that seeing an ad when I'm on someone else's hosted page is (somewhat) acceptable unless I'm a paying customer, but seeing it on my own machine isn't.
In the end since those are two entirely different things and the article seems to be discussing their hosted version, It's important to keep those things apart
