Who changes the rules

Everything is routine and life is not in chaos.  Who changes the rules?  Go to a store.  Find the same brand of green beans and then somebody changes the label.  Buy the same dog food for years and someone changes the color.  Buy all these fancy new rulers, helpers and books and go back to the way grandma made the block.  Up and downs.  Around and arounds.  And, darn it, I'm forced to upgrade again.  I'm so glad I have my baby Bernina and have had her guts replaced.  10 more years and I won't have to upgrade.
