What is a joke? Foldable phones have existed for years at this point, if anything Apple is catching up. And plenty of people want bigger phones.
And even when they do use it unfolded, whatever they’re consuming has two huge black bars top and bottom. This may change as content creators adapt.
What Huawei and Samsung have shown is that there is little usecase to foldables. And I do not believe Apple can create any usecase not already known.
