Sorry if someone is so poor that they can't shell out $1+ they shouldn't be wasting even 1 cent on games and probably should sell their PC to buy some food! They certainly can't afford to pay a broadband subscription to cover their Steam costs.
Just because someone can't afford non-essentials doesn't mean that they can't buy food or don't need PCs/broadband for easy access to jobs and such. I know quite a few people in those situations (and I'd think that most people at least in the US know someone) so I guess I'm a little more understanding with the economic situation the way that it is that but for the grace of God that I could be in the same situation, and how much entertainment helps to stave off depression and make the situation a bit brighter. So done within reason, I can understand prioritizing a little entertainment- and that's why as a gamer I try to do these unexpected things for friends in those situations. Economic hard times haven't spared any class of people during this downturn, and I know people who've worked hard for 20 years+ that have lost everything because of it. And some are *still* not turning to handouts, so isn't a charitable attitude towards them just as much charity?
I am sure not everyone is gaming the system but obviously a lot of people are otherwise they wouldn't have made the current statement. Another thing they can do is simply wither stop using Steam to avoid the issue - all the games are still downloadable and playable which seems fair enough - or ask Steam to make it clear that Humble Buindle Keys are not going to be eligible for any prizes etc.
I think the issue is being clouded as far as that is concerned. During Steam events, sometimes you need to buy a game to complete an event. Some people are getting the games exceedingly cheap in order to be able to compete in these events. That's the issue, I think- not that you can use the keys to be eligible for prizes. And to stop using Steam would punish the many for the sake of the few- sort of like DRM in a way...? But that's a different discussion.
