Answers for both direct to USB port of laptop, and for USB-C to Ethernet adaptor entry please, if it makes a conceivable difference. I feel like there's less chance of collateral data sharing via Ethernet port?
To clarify, this is using your LTE only phone as a tethered router. The data connection relies solely on a sim.
Laptop system is qubesOS, so there's quite a few levels of separation between browser and network. And it would only be used for anonymous disposable browsing or otherwise 'unimportant' sign-ins like Netflix, and even then, through laptop VPN.
Would you trust direct tether to your GOS device?
These all happen on different network layers right? The phone OS shouldn't meet with the transport of data from the laptop (encrypted before leaving the laptop because it won't inherit any GOS VPNs)
I'm preferring GOS overall since adopting it. And I have faith in the sandboxing, but I miss the comfort of spinning up a disposable VM.
