I just did. It was in the post you are responding to. They just spent 14 months since datalock without wasting time responding to attacks. If instead of doing the things they have been doing, they wasted time responding to pointless allegations in the vain hope of keeping the stock price up for shareholders at the expense of patients, then two years is a pretty conservative estimate.
So, you are thinking that NWBO is only doing one thing right now? I think it is pretty clear that they are doing quite a few things and adding unnecessary things comes at the cost of things they are doing now, without any of the benefits.
