The proof is in the article. They are claiming to be someone they are clearly not. You can say “we remain anonymous”. Fine.
But they are saying “Look this is us. We have a picture even and smile at you. We worked at apple and we put really specific titles to it. We even claim we “lead the development effort on Siri” at Apple. Now please invest money because we were at apple”.
That is not remaining anonymous. Remaining anonymous would be a CV on linked in without a picture calling themselves Peter Smith 1 and Peter Smith 2 and putting on their cv not specific dates and universities you never went to.
Remember: nowhere do they say that these two are not real. They say “meet our founders”. And then they collect millions in USD from investors.
That alone is not okay and I can’t believe you seem to think so. All this would be fine if they said: this is what our founders could be like but we wish to remain anonymous. However they are raising money using these fake CVs pretending it is them.
