Facebook's blatant rip-off of Bitmoji avatars is a legal lesson in skirting copyright

Facebook fastidiously copied Bitmoji's artwork for its new avatars feature. Consider a) the access to legal expertise and b) the shameless indifference Facebook has to ethical standards, bad PR or media exposure. In this image (posted to twitter by Alex Heath) is a detailed lesson in exactly how closely you can copy others' work and get away with it. Or if you prefer, it establishes the necessary quantum of difference to avoid liability, in Facebook's calculation.

Google reportedly has the same mentality. It's not "plagiarism", it's "don't re-invent UX."
