People should not be forced to keep continue under extended situation. There should be option for those who wants to quit at this stage to be calculated at old percentage and those want to carry on participation should be treated under new percentage. There should be choice for everyone as till February is too long for many people.
I agree, every campaign which gets significally extended offers to people the possibility to step down and to keep the earned stakes. People commit to a project based on initial conditions, if they change people should be able to change their plans too.
