I'm going to see this a bit differently to the rest of you... John is probably going through one of the worst periods of his life, he has a wife & new born baby many 1000's of miles away from where he is, he has apparently lost/forced-out/left the company he started (his dream) & his Mother had invasive brain-surgery last Friday... so I would assume he's in a pretty emotional place at the moment & has a lot to deal with one way or another.
I can see both sides of the argument but the spite & hatred that is within some post leaves me scratching my head.
DBS surgery is not something anyone would undertake, it is high-risk surgery that has three outcomes, relief from the symptoms (not a cure), no benefit so the operation has to be reversed & lastly 'brain death'.... the operation consist of having two holes drilled into your skull, a four hour operation to place wires inside your brain (one bleed, it's lights out), for the entire process the patient is 'awake'... The second part of the surgery happens 2-4 days later when the patient has to undergo further invasive surgery to have implants fitted under the rib-cage/collar-bone to have the whole thing connected up. There is the a ten-day assessment to see if things are working properly & the bodies reaction as the implants can be rejected (the operation is reversed if this happens)... basically someone else is playing Russian roulette with your life after you have handed them a gun.
We all do things unintentionally on these boards, I had a emails from John on Friday & Saturday with regard to his Mother's DBS surgery, they were highly emotional... people don't see what happens behind the scenes, whether you like John or hate him.... I would suggest a bit of compassionate latitude wouldn't go amiss.
