I mean, he's... technically right? Netflix could start showing ads, and increase revenue (either from creating a lower price tier that encourages more adoption, or by adding ads to the lowest price tier to increase revenue).

Of course, that's also the same logic that hundreds of tech companies have already "figured out" about ads. And it always ignores the knock-on effects of ads seeping into other price tiers, of ads taking priority over other features, etc. etc... that eventually destroy entire platforms and pieces of software.
