Hello,
I cant figure out the meaning of 28th-29th paragraphs of
BBC article "Digital do-gooders: Why do we help strangers online?"
BBC News - Digital do-gooders: Why do we help strangers online?

Could you explain the meaning of following sentence?
"Is it altruistic? That's a bigger question than I'm willing to take on,"

Followings are 28-29th paragraphs of the article.
There are also purists who see writing code as an art form in itself - it can be "ugly" or "beautiful" - and strive for ever more elegant forms of code, according to author Steve Weber, who has written on the success of the model.

"Is it altruistic? That's a bigger question than I'm willing to take on," he says. "But I think it would be wrong to assume that there isn't a meaningful set of people who just think 'Hey, I'm going to do this and give it away because it's good for the world.'"


I'll be grateful for your help,
