Slack doesn't deserve any hate here... also, it happened in 2018!
I created this manyyyy years ago, since finding/uploading new emojis was so clunky. It's so weird to see it here now. This whole thing happened in 2018, so this isn't new. They just wanted me to change the name (fair enough!). I always meant to redo it with their new emoji API (so it didn't need a Chrome extension) and rename it; I just never got around to it.
Plus, their emoji support got better (they used to reject large emojis rather than resize, didn't have newer emojis, they didn't have an API for adding emojis, etc), so a lot of the features became much less important :)
The email from their lawyer had a bunch of scary legalese, but here's the friendly part from him:
"Please understand that we are not interested in squelching creativity or stopping people from encouraging the use of our platform. However, our name and our brand are very important symbols of trust for our customers and we need to make sure that trust is not violated, even inadvertently, by non-Slack products."
I'm a huge Slack fan (hence why I built this) and built this to fix a need I had, but it's their brand and I don't blame them at all!
