For people who don't sell on TpT (and even for a few who do), it's pretty common knowledge. If you download a freebie you don't like, for whatever reason, the kind thing to do is to trash it. Just don't use it. No one is forcing you to. You didn't pay for it. Just throw it away and forget about it. It takes seriously about 3 seconds (FYI I just timed myself throwing something in my trash).
When someone gives you a gift you don't like, do you tell them what's wrong with it? If your mom raised you like mine, you simply say "thank you" and move on. Or, as we like to say in my 2nd grade class, "YOU GET WHAT YOU GET AND YOU DON'T THROW A FIT!" Maybe regift if you know someone else who will appreciate the gift. Well, just like in real life, negative comments and feedback on a Teachers Pay Teachers FREEBIE is just plain rude. It's hurtful and makes sellers like me not want to post ANY FREEBIES. You heard me. If my rating goes down, I start to feel like I don't want to give anything away. This is truly unfair to the rest of the people who leave positive feedback (THANK YOU!!!), so the jury is still out on this. So, to recap, if you aren't completely satisfied with a FREE item you find...suck it up and feel free to MAKE YOUR OWN (gasp!). End rant.
