What is the current state of the law on a probation order allowing a defendant to access the Internet on his computer and other electronic devices?

"grants defendant the ability to access the Internet on his computer and other electronic devices so long as he obtains prior permission from his [probation] officer." (Id. at pp. 1349-1350; see also United States v. Rearden (9th Cir. 2003) 349 F.3d 608, 621 ["The condition does not plainly involve a greater deprivation of liberty than is reasonably necessary for the purpose because it is not absolute; rather, it allows for approval of appropriate online access by the Probation Officer"].)
