I wrote a1ex in a pm but I didn't get a reply.
I couldn't find any message from you, neither PM, nor e-mail. Anyway.
I'm from Germany and have a 5d4, but I might be willing to lend it to a ml guy, but my main motivation is for raw video, 1080p would be fine first.
In my case, the main issue is not lack of hardware - that's relatively easy to get on the used market, or borrow from a friend etc. The biggest problem, in *my* case, is the allocation of large amounts of time for hobby projects (estimated
several hundred hours required for a working port,
not including maintenance). I'm
no longer able to allocate this amount of time without risking my ability to put food on the table. This wasn't an issue before ~ 2017, but living expenses increased a lot in recent years (they doubled this year, for example). I'm already looking for a second job (tried freelancing, without success, but still considering it), and having an extra 5D4 to take care of, is definitely not going to help, as it only means
additional workload for me. Even if I'll be allowed to sell it afterwards, I still won't be tempted, sorry.
In other words:
Need hardware + time.
Hardware is easy.
However, that's my motivation behind
Open Collective - if it works out (unlikely, given the reverse engineering nature of our project), and if I'll be able to cover at least a significant part of my
living expenses out of that, I'll reconsider. Otherwise, I'm really sorry, but this port will have to be created and maintained by somebody else. Same for all other cameras that are not yet supported.
So, if other developers are willing to look into it and can prove their skills first, preferably on another DIGIC 6 camera, OK from my side. Just be careful with lending - I won't be able to guarantee they will succeed, or that they will actually return the camera afterwards

C log in 5D IV is just an on/off feature in the firmware. Same as language restriction or WiFi/GPS.
Possible to change with Tornado EOS but I also suppose A1ex could do the same.
As for C-Log, if it's a paid upgrade, I wouldn't touch it, no matter how trivial it might be to unlock. It would be software piracy, which could upset Canon and put our project in danger.
