Would a drone fixed to a zipline or other such stationary point be subject to the same rules as an untethered drone? A simple yes or no is the preferred answer.
Legality of tethered or otherwise attached drone.

Tethered drones using powered flight do not fall under the category of balloons and kites according the the FAA.

I'm always nervous about documents without a date, name of the issuer, or contact information.
Here's §44806, Public unmanned aircraft systems, of the U.S. Code from the U. S. House of Representatives. Note that the title is different and the contents are different from the linked document. I'd rely on the House version.
EDIT - ADDED MISSING URL
Does anyone know what a "public" means in "Public actively tethered unmanned aircraft systems? This section seems to focus on public agencies. Is this applicable only to drones operated by public agencies?
(I'm still wondering about the "why?" of attaching a drone to a zipline.)

I've not read the documents, but wonder about the term "actively tethered" — whether it means a tether that conducts electricity so the aircraft need not loft a heavy battery. Might be relevant, might not.
"actively tethered" means the tether is supplying the power. If the tether breaks, the drone falls.

§44801 (7) The term "public unmanned aircraft system" means an unmanned aircraft system that meets the qualifications and conditions required for operation of a public aircraft.

§44801 (1) ... The term "actively tethered unmanned aircraft system" means an unmanned aircraft system in which the unmanned aircraft component—
(A) weighs 4.4 pounds or less, including payload but not including the tether;
(B) is physically attached to a ground station with a taut, appropriately load-rated tether that provides continuous power to the unmanned aircraft and is unlikely to be separated from the unmanned aircraft; and
(C) is controlled and retrieved by such ground station through physical manipulation of the tether.

I've been unable to find any reference to 'passively' tethered drones, i.e., simply fixed to a stationary point. §44806 refers to Public Actively Tethered UAS, and the rules seem similar to untethered drones, with some differences.
@Vic Moss I respect and admire your knowledge and experience. Please help me understand why a tethered drone would be considered "not flying" in the NAS.
Excerpt from §44806:
(T)he Federal Aviation Administration shall permit the use of, and may issue guidance regarding, the use of public actively tethered unmanned aircraft systems that are-
(A) operated at an altitude of less than 150 feet above ground level;
(B) operated-
(i) within class G airspace; or
(ii) at or below the ceiling depicted on the Federal Aviation Administration's published UAS facility maps for class B, C, D, or E surface area airspace;
(C) not flown directly over non-participating persons;
(D) operated within visual line of sight of the operator; and
(E) operated in a manner that does not interfere with and gives way to any other aircraft.

I did see that. And it immediately raises the question, "What is a public aircraft."
My understanding is that they're referring to aircraft and SUASs operated by public agencies, such as fire departments and such.
