Personally I think that financing a platform like this with premium subscriptions is illusory. I could be wrong but what are they going to offer as a premium?
I think it may be interesting to note that Spotify is closing its first green year in its history this year, for reference.
I'm not going to discuss it with you, because I'm not a doctor nor is it the issue, but the health authorities (at least the European ones) do not agree with your statement.
