The whole thread is full of people who don't HumbleBundle or donate to charity having strong opinions about both. They think that because the site mentions charity that they should be given free stuff for tossing $10 to a charity and that humblebundle must be greedy for being the only business that donates any of your purchase to charity.
The developers are taking a big revenue reduction to support a charity not Humble. If this is the recent bundle than what Jagex is selling normally costs more than $190. The default should favor the charity not Humble. Humble is just mooching of Jagex’s goodwill.
Our mission is to support charity while providing awesome content to customers at great prices.
Their first and thus apparently most important reason for doing all this is "to support charity".
If we go by the screenshot alone, it's $12 of which only $0.60 goes to a charity. Which is 5%. Compared to $3.60 or 30% for Humble. I'm not gonna include the developer's fee because the developer is not the one claiming they're doing it for charity - they're obviously doing it for the money first and foremost.
Sure, more than nothing, but taking 30% is shady enough, IMO.
It's all about the intent. Steam is there to sell you games. Humble is there to support charities while giving you cheap stuff. In their description the charities are the first thing that gets mentioned. And then they give them 5% of the money.
What I'd want? For them to give at least half, not measly 5%. Come on, they're bragging about giving to charity while really not giving them 95% of their income. Like, at this point I'd rather donate the $12 to the charity myself than support yet another parasite on the donation system.
I donate to various things regularly (mostly stuff local for my country, but some international as well from time to time), be it charity or open source projects, and I hate when everyone takes a cut out of this. But at least most of them have the decency to send most of the money further, not only 5%.
I'm negative because I don't see anything positive on a charity gaining $0.60 when $12 was given to the one who collects the money.
