i do agree that there's something weird going on. Seems like someone is trying to prove a point that if you fork away, you are making yourself vulnerable to 51% attacks. not pointing fingers but it seems awfully suspicious.
Not sure what the fear of the z9 is all about, odds are it's nothing more than a z9 mini with 3x more chips and 3x more power consumption. If the asic chips are expensive for the Z9, makes sense to sell "mini" versions at $2k vs a full version at $6k.
