It’s generally a question about what’s best for the user, your general user would likely be more mad losing all their messages because they forgot their password then they are calmed by the fact that no one else can read the data. Same for photos and files, however for sensitive categories such as health and passwords they are always end to end encrypted as it’s determined it’s worse for anyone else to get that data then it is for the user to lose it.
For anyone that truly cares to have complete encryption there is advanced data protection but for the general users the defaults are a good balance between security and ease of use.
