1. It runs through Telegram. Packs only come out of Telegram's bot API, with a bot key on a server. Telegram decides who can import, and can turn the bot off any day. That's the gatekeeper Nostr exists to avoid, and it makes my server a middleman.
2. The signature lies. On Nostr, whoever signs is the author. An imported pack gets signed by the person importing it, not the artist. It's someone else's work republished under your key, with no consent from them.
3. Most apps can't show it. TGS is Telegram's own cut of Lottie and no NIP covers it. Posts would show stickers that Damus, Primal and Amethyst show as a broken file. Nostr works because everyone can read the same simple things: images by URL, NIP-30 emoji as PNG, GIF or WebP.
The Nostr way: artists publish their own emoji sets under their own npub, and anyone adds them to their list (kind 10030) by reference. We could support that: show NIP-30 emoji and animated WebP, and let people add a set from a link. No Telegram, no key, the artist stays the author.
