The automatic updates only apply to minor updates, so you can still "get paid" by updating a major update. But regardless, if you're a developer you can disable them but the user or client can update their site themselves, so they can still "not pay you" if they wanted.

You should be getting paid in any case because you either tell your clients that if they update on their own and something breaks then they have to pay you to fix it, or to pay ahead with something like a maintenance package where you just go in and take care of their site for them.

We have disabled all the automatic updates for our clients and fortunately have not had any update by accident; I would double-check your plugin. We're using an MU plugin that adds a filter to accomplish it.
