This project isn't literally scam but as what holydarkness said before that their actions are questionable.

It looks like they don't want to be responsible for this delayed development deadline and just like avoiding pressure from the community. Even they have some supporter (I don't really know whether they're a real people or fake or just bots) in their telegram group that gives pressure or make people who protest about the integration become like a bad guy or FUD-er.

They threat the community arbitrarily and don't even want to tell the community what exactly they're waiting for or what's the reason for the delayed integration.
They just said that they will announce news and never say any details about their current progress.
