@Scoox - I can imaging having the service blocked is a real problem for you!
I, too, think that we should be allowed to have local projects, but I'm not sure if they are not mining the data or not. I certainly wouldn't put it past them, they wouldn't be the first. My instincts are to trust them, or I wouldn't use the software, but the thought is always there for me (my projects are mostly hobbyist anyways at this point).
I have never joined Facebook because I knew they were data mining and got in a heated online discussion of that very subject about a month before the whole thing blew up.
As a Computer Tech for 38 years I view things differently than most people. Given the Chinese government's repeatedly getting caught stealing US Companies' data I would not be so sure that these "blockages" you experience aren't really a case of them routing all the data through a Chinese server on it's way to and from AutoDesk's Cloud, something I'm sure gives the AutoDesk Cloud Managers sleepless nights.
Granted, the data flow is highly encrypted and even breaking one single transaction would take them a considerable amount of time, money, and effort to crack, something they certainly wouldn't invest in for 99% of the stuff being worked on. (READ THIS AS, YOUR DATA IS ALMOST CERTAINLY SECURE ON THE AUTODESK CLOUD!!)
Still the possibility is there and it certainly makes the big companies like Aerospace firms and the like hesitate in choosing AutoDesk over off line solutions.
Twenty years ago this wasn't a big deal, but in 2018 ...
