Okay, you say this but you haven't supported any with that free Ink. Also, this isn't about the Ink earned for free. This is about the value it loses when purchased.
Also, the piddly amounts of ink you get from watching videos is ridiculous. Just 10 ink per video. That's less than a penny. And that 40,000 is only a bit more than $33, before fees.
And again: this isn't about free Ink. It's about the vast discrepancy between purchase and donation values.
