Certainly diffuse axonal injury typically results from rotational forces or massive deceleration. These induce shear between grey and white matter due to the difference in their relative densities. Had Bianchi sustained a direct blow to his head at the speed he was travelling, I suspect he would died at the track side from devestating head and cervical spine injuries. Massa may have been protected by a canopy, as might Henry Surtees, but I don't think such a device would have changed the injury sustained by Bianchi.
The HANS device helps to reduce base of skull fractures due to unchecked head movements from severe deceleration at the moment of an impact, and a crash helmet increases the distance over which deceleration occurs when a moving head strikes a solid object. However, nothing can absolutely prevent the brain moving within the skull nor shear within the brain substance itself. The problem lay in the nature of the object struck by Bianchi's car - such an immovable object dictated a huge change in velocity over a very short distance.
Looking at one of those videos again, the marshal was waving double yellows but changed to a green flag before the tractor cleared the track. He kept waving it for ages after Bianchi's crash too, which is even weirder... Maybe an inexperienced marshal. Might never know if Bianchi's driving was influenced by the flag as he may not even remember the crash or the preceding events. Nope he's getting better...
Agree that from what we know about this particular incident a closed cockpit would have made very little difference. Here's hoping He recovers.
F1 was just getting interesting again I don't belive it needs a major change to the safety regs, as a result of this crash. More a tightning of local proceedures, on race days.

For the force of the impact to lift and throw off the other car from the hoist it's almost certainly a very high energy impact.
At the height of the top of the main bodywork the impact was definitely taken by the driver.
Horrific, and why on earth was there such a heavy vehicle on a run off zone while cars were still under race conditions, even on double yellows they were still racing. Modern F1 cars could be lifted safely by a long reach all terrain crane from well behind the crash barrier.

Having seen the footage, I feel that there is more going on with the car than just aquaplaning, first of all it appears as if he had deliberately aimed for the big yellow crane, and no I'm not actually purporting he did, but he hit it as straight as an arrow with very little to no skew. And whilst it is physically possible to aquaplane in a straight line it's rather improbable, as in each wheel has to slip at the same time and by the same degree and the car has to be traveling in a straight line.
Interestingly he was 10 seconds behind the nearest car in front, he wasn't racing anyone behind, was running in 18th and it is being rumored that he did not lift for the double waived yellows.
So my money is on mechanical failure and not driver error.

Given the straight line it most likely to be a rear end failure if any, so maybe it's the energy recovery system failure that we saw with Lewis before. Failure seems to seize the rear brakes and make the car a missile.

That is a very impressive video. The main problem I foresee would be in the event of a fire. Thankfully, that is a rare occurrence.
I have seen no evidence that Bianchi suffered direct violence to his head. The crash footage is inconclusive and photographs taken during his extrication from the wreck show his helmet to be intact and unblemished. As I've said already, diffuse axonal injury is usually the result of indirect force through extremely rapid changes in velocity with resultant sheer between tissues of differing densities. A direct blow at such high speed would have caused a very different type of head injury and likely devastating (perhaps even rapidly fatal) cervical spine injuries. A canopy of any form would have been ineffective in protecting Bianchi in this instance, but I am not averse to their use in principle.
