The question is "as a parent, would you buy an {x} phone for a young family member that suggests profanity?"
As an adult, you can go in and add the words that you want to use yourself... however, do you want profanity to be a default suggested word for children in your household?
Realizing that the demographics of HN tends to the more technically literate, removing the all the words you don't want your children accidentally sending to their teachers wouldn't be a big issue, however as most of the population isn't as technically literate the "it just works" mentality for digital appliances would mean that most of the population that has a child who may use the phone would likely opt to one that is more proper and correct in its limited word choice.
Kids have Android phones, so yes, it is clearly the case that most parents have no problem with this.
Not "can you go in and unblock profanity suggestions" ( https://www.laptopmag.com/articles/disable-android-offensive... ) but rather "is this the default"?
It's no way to treat adults.
