For years people have known it can’t be upgraded. You know that going in.
Not sure that is true, lots of people see the marketing for a MacBook and think that any of them will be enough. Or see the price difference and think they are getting a good deal, or don’t understand why that is. I’ve had to tell people, sorry I know you spent a lot of money on this, but it does not have the storage for what you are wanting to do. Yes, the only way is to buy another one.
Otherwise yea, everyone tries to gaslight customers into thinking they didn’t get ripped off.
