IMO, one of the biggest scams in the mobile space currently.
My old OnePlus 3T flagship from 2016 came with 128GB of storage and it "only" cost €480. Also, best phone I ever owned by far BTW.
Today, nearly 6 years later, Apple and Samsung flagships (I'm staying away from OnePlus nowadays) are charging huge markups for more than the base 128GB of storage, on phones that already cost €1000+, despite flash storage getting significantly cheaper since 2016.
This is beyond insulting, especially since modern flagships also lack microSD expansion.
