It does create some bad incentives for that company.

(While creating really good incentives for other companies to come along and offer their own insulin, or ice cream that doesn't make you need insulin.)

But I don't find it strange that the customer decides they'd rather buy insulin than not have insulin! That's not stockholm syndrome!

(And don't say "stop buying ice cream", for the analogy to work the original product has to benefit the buyer even with full knowledge of the consequences.)
