I could certainly imagine Patreon making a pitch to bigger creators about taking control of their own destiny and keeping more of their money. Would it work? I don't know. But a single creator who averages $1M a month is twice as valuable as a thousand creators who average "only" $500 a month. If you're idealistic, you may still prioritize the thousand, but if you've taken multiple rounds of VC money at a multi-billion dollar valuation, you're gonna look real hard at what you can do to bring in that one.
In other words, no one who can average $1M a month has anything more to gain from moving to Patreon’s platform, or any other payment processing platform for that matter.
> less than 4% of Patreon's total number of creators make $1K or more a month, but they account for about 70% of Patreon's revenue.
That describes the shape of the curve, but doesn’t describe the total volume. If the overall market size is increasing, which it does, regardless of the thin long tail, their aggregate revenue will increase. It doesn’t need to do anything special, it just needs to make sure it is not going to lose its share of the ever growing pie.
No one that can be Taylor Swift or Lady Gaga needs Patreon because they can already monetize their content through mainstream channels. There is no to little value Patreon can add on top of that. Patreon exists to enable monetization for the long tail of creatives, which means they need to increase breadth, not depth, and not lose the current growth in demand for these channels to competition.
