I'm not sure that the OP was "outraged at a person's lost productivity". It seems like badv0r may have thought that the project could have potential merit if it focused on something like "feeding 80 human beings in poor country" instead of "Buying random things from amazon each month".

To be more general, the bot currently buys:

<unneeded thing> for <person who can afford it>

while it could buy

<needed thing> for <needy person, who can not afford it>
