yes,they can。they shouldn`t sell over the pts 1.0 to the market ,and give future DACs to pts 1.0,and pts will die. let pts die naturally
The way I read it, Invictus wants pts 1.0 to die, but they can't tell you or force you what to do. So if the majority stubbornly loves PoW and sells off their DPoS pts 2.0, then the market will let pts 2.0 die, without Invictus being able to do anything about that. The community / market really will decide and if it chooses pts 1.0 over pts 2.0 then bitshares or Invictus has no choice but to honor that decision. Also future DAC developers will have to adapt to that situation as well.
I see that people are confused, but this is not the usual central planning kind of upgrade and even with traditional central planned monopolies upgrading can't be forced on the users. Look at MSWindows. How many versions have there been since WindowsXP, but a very significant amount has chosen to stick with XP despite all the power and centralization of the MS-corporation who are the sole owner of the closed source and control absolutely everything. That community choice has forced MS to change their plans and honor the wishes of their customers against their own wishes and reintroduce things like a start-button that does not distract or disrupt your work-flow.
In short, Invictus
has no choice but to respect the wishes of the majority and if the majority/market wants PoW-pts 1.0 then that's that. Even if Invictus wants it dead and buried the second pts 2.0 goes live, they have no real power over that decision, other than trying to persuade people and exchanges to go with pts 2.0.
