I’ve used it for the exact same purpose, great minds think alike. It’s perfect for that scenario given there’s no internet.
I just don’t use it much otherwise because apps like Signal are far easier to move my friends and family on to and they’re more than good enough. The metadata privacy Tor would provide would give me a lot of peace of mind but I know it’ll never happen.
Good to know the name, I’ve seen it invoked a few times.
In fact, I had this recently at work where I questioned a decision only for them to retort with one similar characteristic which a prior suggestion of mine shared. This was also a modal fallacy as they only used that one characteristic to come to a conclusion about both.
You also see it all of the time in politics unfortunately, a lot of “yeah but you also…” where we should be hearing good justifications.
