Pardon my cynicism if I think it's likely Apple and Netflix.
And they probably do that for everyone only because it doesn't eat into the main profit generators in their business models. Not many marketers paying Netflix to advertise their new natural soap line to targeted prospects I'd imagine.
I agree about the buzzword part, but the parent did specify two FAANGs. I'd think it would be interesting to hear which two since it's obviously not Google (as the article hints that they want to move data out of the EU).
Also, the FAANG expression didn't start around scale, if that was the case netflix wouldn't have been included as early as the expression was coined. The expression was about developer compensation. That seems to have changed recently(-ish) though and now the expression is more like "unicorn" instead of just the specific companies that make up the acronym.
(EDIT: That would indeed be Apple and Netflix, as hinted by another comment).
