Tesla has control over the system (OTA updates), you "have to" bring it to Tesla for repairs and service, and they've even tried to control who can resell a cyberteuck.
That's not the case at all. I haven't needed to do much on my Tesla but the few things that I have needed to do on my 2018 Model 3 have been handled either under warranty by Tesla immediately and without charge, or handled by the same body repair and tire shops I took my Honda to before.
As for the Cybertruck resale limits, other manufacturers do the exact same thing for new models at initial launch or even as part of their regular sales agreements. That includes traditionally more expensive brands like Ferrari and Lamborghini, as well as brands like Ford when introducing new high end models like the GT. This isn't something weird in the industry at all for new limited production models.
