Probably people realised that in many cases, a chatbot simply wasn't a good choice of interface for the product/service they were building. Yes, they can work well in some cases, like with help desk type support, sales, general gimmickry on chat rooms and forums, etc. But in a lot of cases, a traditional UI (whether visual or command line focused) is simply far more usable than a bot, and people/companies realised that. As much as it may sound old fashioned, talking to everyone is not necessarily better than using a keyboard/mouse/controller/whatever, and having a bot that has to figure out what you want with far less sophistication than an actual person makes it even worse. The technology isn't there yet for chatbots to be as useful as they need to be, and in many cases, bots and chat interfaces and what not simply aren't a good solution for the problem at hand either.
