The fact that we have to go as far back as CD players for a decent example illustrates my point - the "CD player" content distribution model is long dead, effectively nobody sells CD players or devices like CD players, effectively nobody distributes digital content on CDs or things like CDs (like, CD sales are even below vinyl sales) - almost every currently existing product receives content through a channel where updates could trivially be sent as well.

And if we're talking about how new products should be designed, then the "almost" goes away and they 100% wouldn't receive new content through anything like CDs, the issue transforms from an irrelevant niche (like CDs nowadays) to a nonexistent one.
