I think the sample size is way too small in the first place for any accurate conclusion (not limited to specially separate the air-drop and investors). I have not received it too but it won't make a difference posting over here because the kind of tone that they are using in their email messages sounds albeit towards the arrogant side.
Pretty much, very bad attitude IMO and no one's responding to the business regarding leftover tokens now, i think they are hoping it just gets "swept under the rug" now and everyone will forget about the issue regarding leftover tokens...I feel bad for the people who legitimately took part in this and received nothing, it may be true they are starting to present "scam-like" behaviour. I wonder what other parts of their roadmap are lies now, will have to wait and see.
