It was niner's project. His threads project was being wrongly attacked, and nobody cared. It was a very strange and calculated attack, when they launched their competing VM. I completely agreed with most of the criticism. But I still think lockless threading would be great to have, as waiting for locks by far outnumbers all CPU disadvantages with the broken parrot calling convention and general problems there. People are still fond of Erlang also, and parrot threading model and implementation is much better than Erlang threads or Go threads and everything else but Pony's.

It's no bad blood though. Hype-driven development has it's place, see rust and javascript. Throwing away unique technical advantages for pure marketing reasons to unite the community against someone else didn't go fine with me. It was no vilification as in p5p though. It was just silly.
