Not true. Apple has a self-service repair program for most of its products, including the iPad mini.
All the repair manuals are available online and you can buy official Apple parts. [1] They'll even sell or rent the tools you will need.
As far as I remember, the self-repair kits only make sense in very niche cases (I think repair shop get a different contract ?) and won't work around any limitations Apple puts on parts or repairs.
It was funny, the guy was narrating as he is searching saying "Whoa, this is the most I've ever seen... Wow, oh man... Hold on..."
I knew it was not going to be good.
I asked if there were any DIY options for me.
He said I could possibly find a used iPad online and swap that screen. But, given the insane prices of the replacement screen, I assume the secondary market for a salvageable iPad that works is really tough.
At this point it makes sense to just buy another used iPad.
