If you use Feedburner and Google closed it, what would you do?

One of the things I've heard over and over from non-technical users who have the same concerns now that Feedburner is owned by Google, is where do we go if we want to switch? Ahh. There is no place to go.

Why is there no competitor?

Here's another question. If you use Blogger or Blogspot and Google turned off RSS/Atom feeds on those platforms, what would you do?

From an old post that turned up in Dave Winer's link blog and came to my attention via a feed reader. Posted to G+ and then copied to Twitter, Facebook and a blog via an Atom feed created by a 3rd party because of course G+ doesn't have Atom feeds.
