Authors using Fair want to share their code while getting protections for themselves. Strong copyleft doesn't care about authors and is all about protecting the end users.
So Fair fullfills an actual need or desire not covered elsewhere, thus is not a non-solution.
It might be not the appropriate or the best solution to solve the exact concerns of people using it, that's debatable and a different topic, akin to using the wrong tool for the job. Strong copyleft is the wrong tool, too; obviously competitors can just deploy without modifications and offer it as a service.

This is a one-sided assertion of fairness, and therefore an abuse of the concept. Free software offers the same rights to both authors and users. That is fairness.
If you want to reserve rights to yourself that are withheld from end-users, that's fine. Arguably even still within a broader conceptual realm of fairness. But naming your personally preferred arrangement of rights "fair" and in so doing implying most or all other arrangements are unfair is just plain arrogant.
Strong copyleft cares equally about authors and end-users. It doesn't disregard authors. Some authors just want to co-opt the general notion of fairness to mean their own licensing preferences.
Call it a non-compete license and be forthright.
