Must have been a tough decision for them:
"Should we use the star inserts?"
"Only if the extra cost comes out of your share!"
"OK, but won't the fine thread bolts just tear out of the soft aluminum?"
"Shouldn't we change the thread to 7/16-14NC and include a set of bolts?"
"You're not listening - it costs money!"
"OK, but shouldn't we at least warn them?"
"Like, tell them we make an inferior product, and they can expect to repair it immediately? Are you crazy?"
... and so it was done.
