@th3f4ult@fedi.666666420.xyz I like #PhoneBooths.
not just the movie #PhoneBooth, but like the iconic #TelH78 (but I can also accept the #TelH90 Only disadvantage is that they are too small for a wheelchair so the #TelHb82 was created.
Personally, I want that classic German Phone Booth back, but better as in *
#Videocalling* and #FileTransfer and being useable as a #Phone with one's own #SIM card and having an #eSIM #VendingMachine to quickly buy #eSIMs on a SIM Card or change them around.
Ideally add like a "bus shelter" or "rest stop" kind of setup around it with #FreeWiFi (#Freifunk)...

@fasnix@fe.disroot.org Und selbst außerhalb von #Nordkorea und #iran, wo Menschen wegen "#Spionage" öffentlich hingerichtet werden wenn diese ne #Roaming-#SIM oder gar #Satellitenschüssel, LNB & -Reciever haben kommt Mensch schnell in den Bereich regulierter #Telekommunikation.
Bspw.: legt @BNetzA@social.bund.de "gewerblich" soweit aus dass sogar rein freiwillige #Spenden ohne transaktionaler Zusammenhang (vgl. #Freifunk) drunter fallen…

@signalapp@mastodon.world Signal IMO has bad security because when someone decides they are not interested in an overpriced, underperforming service of "phone number" and stops using their SIM, they cannot deregister the number from Signal and the new owner of the number either can hijack their Signal account, or people may be blocked from using newly purchased SIMs with Signal.
Also, authoritarian regimes IMO can temporarily transfer a number into a provider's internal SIM in order to hijack a Signal account and impersonate a dissident against another dissident, facilitating abduction, torture and murder.
I feel
c o n t e m p t
towards Signal when it is designed this way.
