Nostr build has a blossom server now, 🌸
People need to understand that, in the vast majority of cases, they are not decentralizing their image or video uploads and that media content isn't actually being stored on Nostr.
The word "Nostr" in the name of nostr:npub1nxy4qpqnld6kmpphjykvx2lqwvxmuxluddwjamm4nc29ds3elyzsm5avr7 build might be part of confusing people. The fact that clients embed referenced content also contributes to it.

Yes, as some other platforms, but the way people are actually sharing media is through links, which clients display as embedded images or videos, so the implementation of Blossom doesn't actually do much.
Blossom isn't the only solution. This is why I wrote "in the vast majority of cases". It's not in every case, occasionally media uploads are decentralized in some way (including the worst: through Nostr itself, by embedding media, in some form, as part of posts, then uploading those massive JSONs to poor relays). Not every case, just, by far, the vast majority.
