I think Jack got the playfield supplier's attention, whoever it is.
I'm guessing here, but maybe the manufacturer accepted some responsibility for the shitty clear? And now Jack can get freebies down the line, starting now?
He can debit each of the replacement playfield he sends out, because he is getting a credit on his very next one ordered?
Make a few dozen phone calls, make some unhappy people less unhappy?
And he is only out the cost of shipping a new playfield.....
