NYTimes takedown regarding my 7-min-workout open app, anyone feels like drawing?

I take it these are the illustrations in question?

Did you copy the files directly from the NYT site, or did you draw these graphics using the NYT illustrations as a model?

If it's the latter, then the Times is in the wrong, IMHO[IANAL]... The characters and poses are generic enough, so as long as you draw them from scratch, I don't think it should count as infringement.

But if you actually copied the files from NYT, then you should definitely take them down.

Woah that blows. Is this your first app?
