So, is the App store not taking 30% off the top (29.68)?
TikTok would end up with $43, and the result is $33. Withdrawing from the Local Money transfer shop is outside of TT, and then after that, I don't know what "TT middlemen" are, but that happens after the withdrawal happens to get the numbers they are sharing.
The shop and the middleman are outside the control of TikTok.
But you can't ignore the app store's cut.
From the article, a $103 donation ended up as a balance of $33 in the TikTok account. If we assume TikTok has not negotiated a better rate (doubtful), then the math looks like:
Donation: $106
After App Store 30%: $74.20
After TikTok: $33
Which puts the TikTok commission at a (still egregious IMO) 55%
A 100% diff. You can argue whether that is fair, but it's a 10% difference.
Or 38% and 31% of the total $106.
So, when comparing the 70% number, we have to look at the actual comparative percentage, or 38%.
So, not 70%, but 38%.
