Doesn’t stop it broadcasting, but stops it being useful to anything nearby.
Any SSID broadcast is useful to Google and Apple spies (read: simple phone patrons) who feed the SSID to the mothership which is then used for mapping. There are security risks by that alone even if it’s blocked from my LAN, which I detail in these threads:
Apart from tracking my residency, I boycott both Google and Apple, so I object to feeding them in the slightest even when it’s innocuous to me. The map data enhances their location products and feeds their advertising surviellance machines.
Anyway, I appreciate your insight. I assumed it was a proactive act by Karcher and would not have thought that they were naive or lazy w.r.t. something baked-in upstream from them.
