We Got Cease'd and Desist'd (2018)
slackmoji.comIt happened in 2018.
Hah! Wow I thought this was https://slackmojis.com/ I didn't realize there was a different app with nearly the same name.
EDIT: Ignore this comment, I thought this was https://slackmojis.com/
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.
