Yeah, I don't think it'll put off the "advertisers" to have to pay such a small "advertising fee", under current conditions of nigh-on global dominence (everyone but me, it seems, using it), but if it doesn't feel like a good deal for the "consumers" to have the optional for-pay features used against themselves, be subject to the machinations of those that have bought into the system but have no real come-back unless they also subscribe...
[Just deleted a dozen rambling paragraphs, and several fetenete! It means I'm not showing my 'working', but it's a subjective assessment anyway. You can equally disagree with the conclusion with or without all this lot.]
...so if everyone is as typical as me (I'd be surprised!) the proposed business model can't work and it'll haemorrhage the passive-userbase, making it less useful for the paying userbase at whatever pricepoint and losing their interest too. Either this means removing some of the "Feemium" emphasis in "Freemium" or doubling-down (to use that old neologism) by raising the entry-fee to cover the net worth being shed (and further accelerating the dichotomy of design).
Having become something of a "meeting on the village common" sort of place, but globally, it has actually managed to get beyond "too big to fail" into potentially "too big to succeed" territory. Under the current model, anyway. Perhaps it could be retransformed into a global common-good [in now deleted paragraphs, I mentioned Usenet; though not in this new context of how it might organisationally/infrastructually be managed]... But, if not, it's surely going to lose out to the Next Big Thing™ in a "morph or die" manner. But not morph in any Musk-compatible way, if I'm any judge. He has the wrong mindset for this challenge. ((All hail Emperor Elon! Honestly, sire, and please believe me when I say this entire post is a joke. Using it against me in my future trial of Retroactive Sedition against Your Supreme Lordship's beneficient rule over the Peoples of both Earth and Mars is truly not worth troubling Yourself over, and I have never been a servant of the Arch-Fiend Bezos. Well, apart from buying one or two or a hundred things from Amazon in the era before Prime, but I didn't know that'd eventually lead to him building his own rockets and landers and eventually carving the Amazon 'Smile' across the face of the Moon, thus insulting Your Serene Empire on a near-daily basis for many days of each month.))
