We are a family of 5 (3 kids in teens, middle school and HS) and 4 of us are iOS and 1 is Android. I believe he did that to be a PITA, and to escape the control I had over him with IOS apps and other stuff.
They're cheaply(and mass) produced, therefore easily breakable. I will say I've been lucky, we don't lose our charge cords often.
I'm curious how you break one of these. Like run over the USB connector with a scooter?
We have issues with cable breaking. Mostly the cord just below the connector at the phone end.
We have a cart we use as the charging station, kept in a corner in the kitchen. 90% of the stuff gets charged and most cords are kept there.
We've had a few break over the years but not nearly as many as some.
I have one of
these stations in the front hall, I bought some short (6") cables for it, so they are of no good use elsewhere and some will charge there. I also have a couple of
these around the house, and they are great for charging while sitting, and they will not be moved.
We go through a ton of Iphone charger cords in my house. My two daughters (20 and 15) either break them or lose them. You may ask, how do you break them? Well, my kids can't be without their phones for a minute to allow it to charge, so they constantly use their phones while it is plugged in. This causes the connector inside the charger cord, where it goes into the phone, to break. I swear they have killed a dozen cords this way.
The other way we go through them is they lose them. They leave the house with a cord and a portable charger and end up leaving them somewhere. I have probably lost six-eight portable chargers this way.
Like one of the other posters mentioned, I got a new Iphone and I put a sticker on my cord to let them know "Don't touch." Sure enough, one day I look over on the counter and it is gone and I never saw it again. My wife and two girls never fessed up who took it.
I am now to the point I just buy a cheap 10 pack of cords and what happens to them, happens to them.
And don't even get me started on the dongle thing that is a lightning to headphone converter for the Iphone 10. My daughter is on her third one in four months with those.

For charging while using (especially in their rooms), I have bought longer cords (10') and chargers that are permanently attached to the outlet (like
this) rather than a small individual charger. For these, I usually purchase the Anker brand. They last a very long time with hard use.
For smaller cords, I have started buying cords with the 'springs' at the ends (like
these), and I have found that they tend to last longer.
For individual chargers, I either rely on the ones that are provided by Apple (bought new phones and an iPad last year or so, and they last well.) I also bought several multiple (~3) port chargers that we use for travel.
For myself, I tend to use a Qi charger on my nightstand and desk, so that helps at night ad doing part of the day, and you don't need a cable (or at least you only need one that stays plugged in!). When my wife gets a new phone and moves into the level of phones that are Qi-enabled, I will get her one for her desk, so she can charge it while working.
