I'm totally guessing but I think there's simply a missing "most" in the first sentence:
> Not only are most patrons not leaving the platform, we’ve even seen many of them upgrade their tiers to support their favorite creators during this challenging time.”
Because as the second paragraph reminds us, there's always some churn. I think what they mean is, the churn rate went up a bit, but it's not increasing (though how they can tell from only one month is intersting).
And btw, it wouldn't surprise me if churn goes up, a lot of $1 tier supporrtes withdraw support to save money, but a bunch of higher level supporters increase their donation by a higher amount. E.g. if you're well off enough to support a creator at $10, you're less likely to need to leave given the current situation, and if you do incresae your pledge, then you won't increase it by $1 - you'll probably increase by $5-$10 at a minimum. So the average income could still go up even as churns are going up.
