I assume it will accomplish helping the FCC realize that some people are upset about interference in the unlicensed bands between popular consumer products from a large company (Logitech) and a larger company (Apple).

I'm not confident in making any accurate predictions beyond that, but it's not my job to predict what they'll do — it's my job as a consumer to report problems to them, and let them act or not as they see fit. Refusing to report a problem just because (made up example) I think they don't care about Bluetooth has a non-zero probability of being a variant of the Bystander Problem. And however likely or unlikely that may be to any of us, it's got better odds than if we don't report it at all. So I say:

Report the issue as perceived, and give them a chance to surprise you with a useful outcome from that.
