  • Thats not a difference. Other clean room projects, for example ReactOS, have source projects that are incompatibly licenced. Its the entire point of clean room reversing, to bypass copyright and licencing.

    The training data is on the dirty room side, it doesnt get passed to the clean side.

    The clean room concept is violated if raw source code is in the model generated, but to my knowledge its not. There is no way to pull out a chunk of the model, and say “This is a direct copy of main.c from xyz project”. At best, you can ask the LLM to guess what it should be, and it’ll regurgitate something statistically close. I just tried asking my local qwen3.8, and did produce a close summary of the nginx main file, but it wasn’t even close to a 1 to 1 copy.

    The clean room would also be violated if you consider the training, model and inference as a singular entity, but that would be tough to argue when the inference can happen on one server, the resulting model isn’t functional in any way, its a big box of data, and the inference can happen on any GPU anywhere else in the world.














  • Detecting motion is relatively easy, but actual positioning would require knowledge of where the WiFi router is placed within the home, and where the other static WiFi devices are. So position detection is realistically about as much as they could do without calibration.

    The xfinity one is more about smart home stuff, and is opt-in (and it’s a fair point to distrust that).

    The reason I don’t think they are tracking motion/position within your home is that there just isnt any useful way to turn that into a targeted ad, and therefore has no viable revenue path. At best, they could count how many times you go to the bathroom, maybe target a metamucil ad, but its so niche (and likely extremely noisy data) that its just not useful.

    They know when your at home already, as your phone will connect to your network, and your network traffic (VPN/encrypted or not) will spike. They don’t need WiFi positioning to determine that.

    I’m not saying people should just trust things are okay, its more that there are much higher priorities to tackle. WiFi positioning is way down the list of realistic concerns.
