I get people even here who just swear up and down it's impooooooosible for them to switch for a littany of excuses. It costs too much (it doesn't, it's actually way cheaper), why would I put them in a remote? (Literally why wouldn't you) They aren't as convenient (compared to buying them at a store?). Or my favorite "they don't work as well" ,which they don't in maybe 5% of cases. So they could still replace 95% of their alkaline but let's be real they just don't want to even try.
They're still there, and usually it's pure laziness, or just arrogance that they don't care about the immense waste.
