I'd disagree somewhat there, they are examples of "sites that are not principally about technology and recur somewhat frequently", and it ends "(choose your own)".

The point is that these recur often and do not specifically have a technology focus, but are current events focused.

The list choices are not really the point either, just examples to highlight the uBO rules.

Also: "So not only are you paranoid about ads but general news stories also?" - I'm not sure what you mean to be honest.
