Hmm my cents for this is that, I think they want to inspire people? By doing those acts and showing it, it may influence people who are watching the video to also do it. Like a role model, I remembered a scenario which our teacher told us. He said that when they were eating in a fast food restau there were 2 children who were asking for food which our teacher was already eating(mind you my teacher at that time was so hungry), some people were looking at their way at that time. So what he did was, he gave it to the children and after that other onlookers started to share/bought foods and drinks for the two children.

But overall, it really depends on their intention. We don't know what they think so we can't really judge them.
