I'm super bummed about this. I absolutely loved slackmojis, it made it possible to find and add new emojis to Slack in sub 10 seconds.
Slack re-doing their UX back in 202X was the moment I realized they were past their peak. Virtually no one liked the new UI but they were too tone deaf to listen to users.
Really hoping some startup builds a spiritual successor and knocks them down a notch, because this cease and desist attacking their very own community to me reads as them being in the "milk the business for all it is worth" stage.
It happened in 2018.
