This speculation is just that... speculation and I doubt it's going to change until there's a new release. Of course this is my personal opinion so feel free to disagree. As I've mentioned in multiple occasions, nobody is hiding the fact that there's been delays.
Excuse me, but how is investor complaining that you didn't deliver something which you supposed to deliver in 2017/2018 (2 years ago) speculation? I find it pretty silly to call the site a scam while things are being worked on. Right now it feels more like pressuring the site to rush out a release just for the sake of it.
So you invest in something and they say they will do something in 2017., you complain in 2020. that they still didn't do it, and you call that a silly accusation, pressuring someone 
Yes, I believe it's silly to accuse of being a scam when a response has been given about how the things that the complaint is about are being worked on. Scam would be if there was no effort being put into anything and everything is simply being left as it is. Then again, maybe my definition of a scam is different than yours.
