This is definitely false. Though some internal apps are deployed on Heroku, it is not the primary deployment target for new projects. Heroku staff work on Heroku. Salesforce has a large internal infra program and team that has no overlap with Heroku. past codename projects have been proposed to change this, but none have ever come to be.
Here's a little bit of trivia... The Visualforce framework (that customers can write interactive pages in, and a small minority of the standard UI is build in) is based on JSF, but most of Salesforce classic standard UI is written in a home-grown system that generates HTML described in imperative Java. It's more akin to an HTML generating Tk.
