Pretty much nailed it on the head here. The biggest issue with unions in tech is that life is pretty good - it's a workers market right now. Why would I give up my strong negotiating position (albeit as a pampered company pawn) to be a union pawn where my negotiating power as an individual is very limited? The one thing you didn't touch on too much is the efficiency of decision making by hierarchical management vs the efficiency of decision making by committee. This is already sometimes painful with processes like Scrum and unions would probably make it worse. The process of negotiating, suing and setting binding legal precedent is so tedious - it can seriously damage companies' ability to move quickly. Plus unions are pretty dated. I have very little confidence that legal precedent around unions would work well in the modern global world.
