I suspect they meant Nvidia, not Netflix; after all, the letters in MANGA are exactly the initials of the companies listed in the post they were replying to.

The N was really Netflix originally when it was the poster child for AWS consumption before NVIDEA/AI was even in the conversation. But, yes, "Big Tech" is probably the best term these days to avoid debates about whether this company or that company really belongs in the category--especially given that certain companies have done very well in terms of stock relative to the the historical FAANGs.
