Try not to take this as me being mean, but I can't help but feel that for profit math education grands very hard against the basic concepts of math and math education("No royal road to math" and all that). I understand that someone of Tao's stature in the popular math community is likely very enticing to masterclass. However Tao himself benefited tremendously from being noticed at a young age and having his skills nurtured. It feels a bit wrong for any one in his position to be aiding a for profit institution, especially when the content is not free. I understand that they approached him, and I and everyone haven't to produce a free good quality version of this. But it does still FEEL wrong. I of course say this as a very privileged elite educated person.

EDIT: in the comments Prithvi has some interesting suggestions for doing a patreon at a higher level to be released freely. If possible and that eventually exists support that,
