> I was surprised by the consumer behavior until I learned
I guess the history is relatively tough to research these without having lived through it, since that's before the popularization of the web.
An interesting more modern use case is Apple's wireless keyboards when they used AAs. I'd suggest you check that out.
> I am not surprised that such a design flaw exists
I'd strongly suggest you consider the complexity, cost, and efficiency tradeoffs involved in RF (and other analog) silicon design, especially in miniaturized consumer products, before characterizing certain decisions as flaws.
Sometimes, worse is better.
> TV remotes are pretty low-drain, to the point that most people probably wouldn't notice their battery runtime unless asked to observe it.
That's my point. What they notice is how often they have to change (or recharge) the batteries. Historically, with rechargeables, that's been way too often.
To be fair, anecdotally, I've noticed this with some cheaper/off-brand alkalines, as well.
> A more compelling argument for NiMH in devices like that would be that alkalines often leak electrolyte that can corrode and damage a device wile NiMH is nearly immune to that kind of problem.
I think "often" is, at best, an exaggeration. Do you have published numbers to back that up?
My impression based on personal experience is that during the normal, useful life, it is vanishingly rare. I've only ever had leakage damage occur from fully-discharged (usually through self-discharge after over a year of disuse), and that was replaced by the battery manufacter, one of the advantages of paying more for brand-name.
