Not saying it is coordinated, but I find the timing suspicious. Feels like it's agenda driven.
Not to mention most of the objections (like in this article) are just arguments from incredulity or traditional. Most are "well it's just impossible" as a presupposition.
It's the kind of low-level FUD that you expect to see in political articles but as they are all presented as an economic article it seems to fly more under the radar (this kind of nonsense writing is usually called out for what it is when it's politics).
Of course UBI is inherently political and, more telling, threatens an entire way of life for some very powerful forces.
Again... not saying it is coordinated, but it would be easy to see why there would be a push to discredit the idea in the US.
