It’s a critique of the name of their newly released statistics, which apparently assumes “what we watched” is equivalent to “what people watched on Netflix”, which may have been the state of things 5 years ago but isn’t the state of things at all anymore.

I guess the comment was more tongue in cheek wrt to Netflix and chill meme but tbh I have my tv running all day (though not just Netflix) just as background noise so ranking shows by number of hours watched may have lots of noise added to it.

You ask the question, however by replying you attain the same value as of the comment above you.

Maybe they netflixed and chilled.
