This is the right move to make. Android is a shithole full of malware. Give your kid your phone for a bit and theyll have downloaded some Zombie Pixel Run 3D game that steals all of your bank info.
Nobody cares about deeply customizing their smartphone or putting advanced software on there, going into developer mode and reconfiguring things, writing custom scripts and automations, etc.
People just want a phone to use. Hence why iPhone dominates in first world countries. They got that part down. Android's PRIMARY appeal has always been that it's cheaper. The people that care about the openness of it are the minority. Even technormies who watch MKBHD or linustectips or something are a minority
