It was known 3-4 months before September 2018 that they would no longer issue VST2 licenses : Steinberg closing down VST2 for good.
In June someone from Steinberg confirmed on that thread that after October 2018 new developers will not be allowed to distribute products making use of the VST2 SDK.
But if you’re completely new to the game then it sucks balls as there was no way of knowing that.
I still think there is an argument that disallowing VST2 hosts for new developers may fall under some EU competition rules, if you’re an EU citizen you could try talking with your MEP about it.
