I was messaged by a Libra(now called Diem?) teams recruiter, went to the site[1] and thought in the back of my head, isn't this the facebook crypto-currency?

I looked through it and saw no mention of facebook or zuckerberg or even any facebook execs. I knew David Marcus is/was a facebook exec, but even he is listed as head of Novi[2]. That right there tells you how damaged that brand(facebook) is when their crytocurrency project doesn't list the company or the CEO(zuckerberg). Needless to say I said thanks, no thanks to that recruiter.

also makes me really question the "a facebook" app thing they put prominently into the whatsapp startup screen. I've heard it was literally just Zuckerberg's ego being damaged because it became so popular compared to the blue app but it seems like a bad move

My understanding is they added this for legal reasons. Users were not aware Instagram and WhatsApp were owned by Facebook and legislators had issue with that.
