1. Masterclass is $20/month. The "masses" can absolutely afford it. It's not really a barrier for entry.
2. There's tons of free lecture content already. Khan Academy is a great example and it'll actually dive deeper than a short episodes.
3. If you're an American, $20/month is laughable for an education. Getting a post-secondary education is like getting a mortgage.
4. Why do we have to knock on highly produced commercial edutainment? It is not a threat to any other form of education by any stretch. At least someone watching this may get inspired or motivated to keep learning more Math.

Agree with your other points, but disagree on this - there are plenty of people who can't afford this kind of subscription (e.g. most materially poor countries in the world, which make up billions of people).
