Saying it the way the OP said is almost guaranteed to hostilize people. But OTOH, it does have to be said in some way--plenty of FOSS people have tried to explain these things to their normie IRL contacts, but those contacts are not willing to hear or consider it--the problem really isn't that FOSS people won't attempt to explain. The problem is that non-FOSS software houses don't and won't explain, leaving people without any clue about the horrible things that can happen once their private data is exposed.

Naturally, most people don't want to have to think for themselves in order to use "weird techie software" when they don't have to (and aren't enabled to do so if they chose) with normal popular software. But just as people who don't pay attention when driving a car are dangerous to those around them, so are people that don't think about the consequences when using computing devices and software.
