Good for them. More curious about file types and protocols, would their software output an open file type and "speak" open protocols? Let's say a French office needs to talk to a US office. Can each party use their own client and it still work, or does one party have to download the software of the other? The same with documents: can each party read the documents produced by the other?

Do parents do not exist? I mean if the parents pass hours looking at their phone, the kids would want to use a phone, maybe making a law is easier than setting an example? Each parent could educate themselves and bloc "harmful" websites from their kids phones, that is what parental control is for.(single, no kids)
