It's very similar to when Google released Google Tag Manager into a field already covered by Tealium, BrightTag/Signal, and others. It's a relatively basic product doing a fairly simple thing, for free. There's tons of space for others to continue to exist in a more enterprise, customizable space.

Also, we (Jetpack/Automattic) would far sooner collaborate with other businesses in the space than compete against them. Which is why when we built this, it's in an extensible way. Over the next couple weeks, we'll be opening up the remote management endpoints for third-party apps to integrate with. That will enable projects like iThemes Sync, ManageWP, InfiniteWP and others to let their users just authorize with their WordPress.com account, and they can instantly control all their WordPress.com and Jetpack sites -- even installing their own plugin from the WordPress.org plugin repository by way of the Jetpack Management connection.

Long story short, we don't want to tear anyone down, we're trying to help build the whole platform up.
