Some things you could have done:
1) Offer to buy the parents a replacement.
2) Offer to take the iPad to a third party to repair. Like Louis Rossman and offer to pay for the repair.
3) Offer to setup a GoFundMe for the replacement or to cover the cost of the repair.
4) Educate the parents that Android is a cheaper better option and determine the best action to recover the data (can be done) and move over to Android.
5) Educate the parents that companies like Louis Rossman exist and can repair Apple devices and to research on the internet for more information.
And yet, you did nothing.
