From the Wikipedia article:

Doctorow argues that new platforms offer useful products and services at a loss, as a way to gain new users. Once users are locked in, the platform then offers access to the userbase to suppliers at a loss; once suppliers are locked in, the platform shifts surpluses to shareholders.[11] Once the platform is fundamentally focused on the shareholders, and the users and vendors are locked in, the platform no longer has any incentive to maintain quality.

And when discussing the solution:

The second is the right of exit, which holds that users of a platform can easily go elsewhere if they are dissatisfied with it. For social media, this requires interoperability, countering the network effects that "lock in" users and prevent market competition between platforms.

It's a made up word that was defined by a specific article by the person who made it up. So yeah, it is.

Locked in and held hostage can defently feel the same.
