Then why do you use alphabet? It's been invented by other people. Please reinvent all those letters yourself if you want to use them. It will be a lot of wasteful work, but you at least won't have reasons to call yourself lazy.
Seriously: We're all creative here. It's the *apples* DeviantArt! I think many people here are capable of making a vector pony puppet themselves from scratch (at least I can). But why the hard work needs to be repeated over and over if we can simply share and cooperate? I suspect that you wouldn't have any problem with using someone else's vectors or puppets if one would post them here (maybe you already did), so wouldn't it be great to contribute to the pool yourself too? Nicoboss143 did the hard work himself, by retracing the puppet from scratch, and he just decided to share his work with us to save us time. Do you think it is wrong? Are you going to stop other people from making use of their own resources and free time because they resemble your work? Don't you think that if someone can do something as well as you, automatically affords for using it? He doesn't claim Flufflepuff to be his own invention/design. He attributed you as a rightful author.
