You left out the portion of the article that says only apps you built yourself don't need to be signed/notarized.

Apps distributed over the Internet, like, you know, the ones we're talking about, must be notarized according to your own source.

What part of Catalina still runs apps which haven’t been notarized or even signed, including those built after 1 June 2019. But you may find them more complex to run

Is difficult to understand? In Catalina just like in the current OS, there is a built in method for the end user to bypass code signing for any app. The user can choose to run unsigned third party code.

The article states that code you create doesn’t have to be signed and you don’t have to go through the “complex” process to run it.

Third party code forces you to go through the “complex” task of ctrl clucking.
