It's not actually vague, if they wanted "everyone" to do that, they'd use "everyone","anyone" or some similar wording, not specifically limit the exception to amateur station. Someone chose that for a reason, and it's a good reason... even licenced hams can cause trouble (eg. forget to turn off a simplex repeater on a radio, "mars mod" it and then jam the fire department frequencies with it,... a few weeks ago), and people who can't pass the simple exam don't need such radios, they can get by with GMRS (if they're from US and able to fill out an online form) for FRS/PMR (if they're not) or even MURS (again in US). There is no real difference in range between an uv-5r and a uv-5g (ham and gmrs radios), and a very small difference with frs/pmr (you need a line of sight anyway).
If someone had a heart attack, somewhere remote enough, that there is no cell signal, using a GMRS radio will have the same effect and range than a ham radio (i'm talking about 5W HTs here). Using something like a garmin inreach would actually get them help, but still, preppers want their baofengs, and for some reason don't want the *g models. That's why i get bothered when people promote ham radios, especially baofengs for emergencies, because they'll be useless in most cases and people who don't know that, will rely on them instead of getting a proper tool for the job. Many of those even have that in their pockets right now (some samsungs and iphone can do satellite communications already). Promoting the "you don't need a licence in emergencies" and then turning to "you'll be breaking the law anyway but who cares" mentality means that people don't learn even the basics (if they did, they'd be able to pass the exam) but still rely on those radios to get help.. and in turn, people will die because of that.
As i said before.. if you have a heart attack in the middle of nowhere, a baofeng won't get you help. If you went with gmrs/frs, you'd test it out and see the limited range and that no one is actually listening out there (unless arranged, and that person is in simplex range), if you get licenced, then you'd do the same, call out cqs into the void until you got bored, but if you do the "just buy one, you don't need licences..." (even if you do need to be licenced), people will be using that radio for the first time during an active emergency and fail in getting help with them. Stop promoting the untrue myth of getting help with a ham radio, instead offer proper tools for the job and people will actually be able to get help.
