People must be smoking good kush in here if you think we 'stole' their logo. I don't even think I've ever seen that logo before. The IOTA logo is the Tangle structure seen from infront. Imagine that you cut a rope/tangle/braid in half and then look at it from the front, that's what the IOTA logo represents; tangle growing toward you. Secondly the amount 'large strands' are 3 = trinary which are made up of further 9 smaller strands = IOTA is 9th letter, you may have noticed the importance of 9 several times in IOTA. So no, we have not 'stolen' anyone's logo.
But we stole rope image, didn't we? Probably we should put some amount aside for civil suits from rope manufacturers...
