You can’t effect the number of bit flips your users hardware has, but you can affect how often buggy code corrupts their memory or otherwise crashes your program.

Let’s say any app will crash about once a year on my machine due to a bit flip. If the app is crap and crashes hundreds of times for other reasons, the bit flip is irrelevant. If the app is robust enough that the bit flip accounts for 10 % of the crashes, that basically means the app is pretty much never crashing due to poor code.
