How is this better than spinning up a free Heroku dyno to serve your node.js app?

Heroku's free service is more limited than it was in 2012. Current policy: "Heroku comes with 750 free dyno hours for development use. Beyond that you must pay for what you use."

That's 750 per month (a nice round number to cover a 31 day month):

How is that different from 2012 (or earlier)? I've had stuff on Heroku for years, never had a problem with this.
