I'm curious if the answers to this would have been different if asked back before ads and/or microtransactions were the norm and every game cost $2-$5

I voted no because a console has a singular purpose. C64 - not a console. N64 - a console. PS4 - almost not a console, but I doesn't have an office suite, a wide range of non-game titles (and I count media players in with games here), nor a widely available toolchain/SDK.

Phones - have an office suite, a wide range of non game things, and several SDKs anyone can use. Hence not a console.

That's fair. I think the interesting implication of this (assuming you answered "yes" for the switch) is that Breath of the Wild goes along side Pokemon and New Super Mario Bros as best selling handheld games, but Angry Birds does not

Although I guess with your definition you could argue that a "handheld game" is not defined as "a game made for a handheld console"

Indeed. A phone is handheld, and had games, but is not a console. A Lynx is handheld, and is a console.
