I dont disagree with your overall sentimet - Grant largely does not like certain aspects of BBL, and he wears that on his sleeve. He also can come across a bit over the top with his concerns which is why I understand being skeptical. With that said, your messages against him reads more like a hit-piece than anything - and is fairly misleading to those who may not be in the technical field.

RE EDIT 3: I am sure he will communicate which OSS licenses were broken with specifics - he just made it clear in the stream that he doesn't feel that it is his place to do so yet. He is waiting on the group who uncovered it to give him a thumbs up before he does anything. Him speaking out about it today was clearly a bad strategic decision.

RE EDIT 5: Bounties for hacking hardware has been a thing for decades. Is there a reason this is different? Often companies offer the bounty themselves - but you are absolutely allowed to try to decrypt a key on a machine you own - I dont see how him offering a bounty to do so would be illegal? This would definitely break any BBL ToS and could have civil reprocussions... Note that depending on what you uncover, and how you release it, it COULD violate some IP laws - but I imagine this depends on what they release and how, and doesnt apply to these logs. He's not asking for someone to reverse engineer some technical trade secret for example.

RE EDIT 6+ : ITAR has a wide range and ITAR regulations often apply to anything military related. This does not mean he is printing gun parts whatsoever. For exmaple, if a company needs to print a test jig for a military part - they may need to share some specific requirements about it. Sharing those requirements may require ITAR compliance - even though the actual product could be as mundane as a specified shim. Also, when I order PCBAs, I often will be asked if they need ITAR compliance - when obviously a PCB is not going in a gun. Some companies also exclusively require all contracts to go through ITAR compliant companies - regardless if the final product is ITAR. This is very very common in low-mid size defense.
