I think the word profiteering may be a bit strongly worded for the general situation. Sure there are definitely people who want to scam others and milk people for all they are worth. But IMHO, those people are after money and the "method" or "content" to get that money doesn't matter... at the end of the day they're after money and dont care about the material they're making. While that definitely applies to some creators, lumping everyone into that category is a bit unfair.
People who have made their own videos and shared them here, they might want to buy a better camera to be able to share better videos. Depending on their situation in life, they may not have the spare cash to do that. So getting a few hundred dollars over the span of a year might be enough for them to grab a used camera.
A lot of this comes down to intent which is really hard to judge... except for looking at someone's track record. If someone has been creating and sharing their work for years... it's probably unlikely they're just trying to profiteer. Someone who's just joined and is immediately asking for money... well that's a very different situation.
I don't think people supporting creators who are and have been sharing openly without demand for money.. shouldn't be considered that the creator is 'profiteering'. I'll admit, this is sort of a personal issue with me, because for over 6 years I've made and given away all my art for free the entire time (I joined here 4 years ago and started sharing here once I did). Meanwhile others pop up in the larger community like the Pleasure3dx person over at R34V and in a few months is pulling in over $2,500.00 every f*cking month via their subscribestar account. If I said I wasn't a little jealous I'd be lying. But I decided a while ago I cared more about sharing my art with the community than trying to paywall it. Which is why Im broke with an older GPU and Pleasure3dx is raking in the money.
No one read that as a cry for support, I'm just being honest and open about the situation. I choose to give away my work freely and as long I continue to make that choice; the consequences of doing so rest 100% on me and no one else. I'm an odd duck... I stand by my principles even though I'm suffering financially.
