That’s not a lathe nor a CNC system. Again, which CNC manufacturers are installing windows + crowdstrike on their machines just so they can spy on their customers? You’re all just spreading conjecture. This attitude isn’t at all as widespread (nor profitable) in low(ish) volume B2B hardware sectors.
These industries have terrible track records wrt security and even software robustness, but they don’t routinely spy on their customers for weird marketing reasons. If there’s remote connectivity it’s for real reasons (eg remote maintenance, updates etc).
The suggestion that CNC machines run internet connected windows+crowdstrike just so the manufacturer can spy on their customers strikes me as pretty ridiculous and your garage door story doesn’t really relate. Much more likely that they do it for (possibly bad) non-malicious reasons.
Because the manufacturer makes sure they don't start up if they're not. Otherwise how else would they be able to spy on you?
