And at what point does FB use their considerable might to replace Slack's giphy bot with one that FB makes? The article basically says that Slack made a special case for Giphy, and so they decided that Giphy in particular doesn't get the same treatment as your typical slack bot or slash command. So, all FB needs to do is block that integration and either force their own or negotiate a new setup with slack. "You have a command called giphy and giphy is our trademark, so stop." The article you link to explains all of this, so I don't think you've refuted my point, really, except to say that it doesn't happen right now.
