I had two popups visiting that medium link with uBlock Origin. Perhaps it is possible to get zero with UBO, but default settings don't seem to be enough.
OP might also be using a list like the "Anti-adblock Filter". You also might want to explore the settings of UBO as there are more lists titled "Annoyances" that you can enable to shut out further garbage.
