Many people who watch their language regard incentivize as a silly jargon word. It means simply "to offer incentives to or for." Some random examples found online: "We ought not to incentivize ignorance of the law." "Professor says legislature should incentivize utilities to improve efficiency." "If you are going to incentivize anyone, incentivize the buyer."
Those who scorn this usage believe incentivize is unnecessary because alternatives like motivate, inspire, encourage, and persuade are readily available.
