Thanks for the info. I adjusted that section a bit, probably should more effort into the edit. Will read up on it some more in near future.

My point about the simplicity of using the "stock*" messesing app is still relevant for non-tech people. Grandpa doesn't want 6 different messesging apps. The easy phone number/pre-installed/near-universal/moslty cross-platform nature of them is a huge advanatge. Only downside, it has a pricy subscription called "the phone bill".

*i say stock in this case to pretty much include any app that uses your phone number and accepts sms/mms from another phone. For most people, thatll be the stock message app their phone comes with.
