Epic had all the money in the world and tons of time (and users) to create a viable alternative. They didn’t fail because valve squeezed them out, they failed because they refuse to improve their product. In fact, it could be said that Epic wanted to become the monopoly themselves. If they spent half as much effort on their product as they do on lawsuits and exclusivity deals, they would have been a viable competitor. But they didn’t. At the end of the day, it sucks to use. Steam does not.
