That "better" analogy is a restatement of "$5 for lemonade, $3 off if you skip the lemon."
> In this case, the discount is "opt-in."
The base price is not a force of nature. $5 with the option to opt-in to a $3 discount sounds great, until you realize that just a month ago the price was $2 by default. They raised the default by $3, but allowed you to opt-out of that increase. Whether you label that "opt-in" [to the discount] or "opt-out" [from the increase], you end up in exactly the same place.
