That's easy. If I don't use it I won't be competitive; however I and probably many others would prefer a world where NO ONE has it as it would be a better overall outcome. For a lack of a better term I would call these "negative innovations". Most of these inventions:

- Require you to use it (hard to opt out due to network effects and/or competitive/survival pressure) AND

- Are overall negative for most of society (with some of the benefit accruing to the few who push it). There are people that benefit but arguably as a whole we are worse off.

These inventions have one thing in common; overall their impact is negative, but it is MORE negative for the people who don't use it and generally they only benefit an in-crowd of people if any (e.g. inventors). Social media for me on many scales is arguably an obvious example of this where the costs exceed the benefits often, nuclear weapons are another.
