If you understand it you can give a short rebuttal as to why it's not like that (you ninja-edited your ad hom out after I wrote this). From Jewpedia:
Quantum teleportation is a technique for transferring quantum information from a sender at one location to a receiver some distance away. While teleportation is commonly portrayed in science fiction as a means to transfer physical objects from one location to the next, quantum teleportation only transfers quantum information. The sender does not have to know the particular quantum state being transferred. Moreover, the location of the recipient can be unknown, but to complete the quantum teleportation, classical information needs to be sent from sender to receiver. Because classical information needs to be sent, quantum teleportation cannot occur faster than the speed of light.
From what I've ever read about it, it's only useful for establishing a secret key between participants, e.g. a one-time pad, but it's not useful for FTL communication. Farther down:
The quantum channel is the communication mechanism that is used for all quantum information transmission and is the channel used for teleportation (relationship of quantum channel to traditional communication channel is akin to the qubit being the quantum analog of the classical bit). However, in addition to the quantum channel, a traditional channel must also be used to accompany a qubit to "preserve" the quantum information. When the change measurement between the original qubit and the entangled particle is made, the measurement result must be carried by a traditional channel so that the quantum information can be reconstructed and the receiver can get the original information. Because of this need for the traditional channel, the speed of teleportation can be no faster than the speed of light (hence the no-communication theorem is not violated). The main advantage with this is that Bell states can be shared using photons from lasers making teleportation achievable through open space having no need to send information through physical cables or optical fibers.
tl: dr: it's just a more secure way to transfer information than other means.
A easier way to think of it: if you entangle two particles, separate them by 100k, or 1000km or whatever, the moment one scientist observes one particle, and shows it has an up-spin, the other scientist, no matter when they observe the other particle, has a 100% chance it has a down spin.
The point is that the quantum state change happens instantaneously which violates special relativity.
It's completely irrelevant to this conversation if it can be used for "communication" or not.
You are one of those pricks who knows basically nothing about a subject but likes to move goal posts, spend 5 minutes googling, and then argue for the sake of arguing. Fuck off.
The article is about quantum "teleportation" of information. That's a practical angle. It's often presented as if it allows something faster than classical information transmission. Practically it's just a more secure system (truly secret exchange of one-time pad, and built-in tamper detection).

Stop getting so emotional FFS.
Moving goalposts? Here's your original post:
We've already broken the FTL barrier in physical experiments using quantum entanglement (archive.is).
I'm saying you haven't broken the FTL barrier. I directly rebutted your claim, and now YOU are moving the goalposts. FTL:
Faster-than-light (also FTL, superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light (c).
Why do you even come to discussions if you're just going to dismiss anyone taking part in it? Feel free to refute anything I've written.
