Developing a fix for a software issue can be expensive, deploying the fix is relatively cheap in today's world with automated software updates.

Compare to e.g. fixing a design flaw in a car, where the development of a fix can be relatively cheap but deploying it (recalling all affected cars to the dealer to have new parts installed) is pretty much always expensive.
