At the risk of sounding pedantic: Twitter's assets were created by its users, not the company. They alienate the users, there are no more assets and no more value to be had.
I think we see it a bit differently. When the grocery store chain sells information about the buying habits of its customers, it is the customers doing the buying, but it was the collection and monitoring systems that "created" the information.
Twitter has "users" but those users are not the "customers". Twitter created a watering hole so that it could interest nearby predators in access to where the herbivores would be on hot days.
To be counter-pedantic (is that a word?) If there were anywhere else for Emojitracker to get their data, then I would agree with you that Twitter did not create it.
