"The way a transistor works is not affected by the way it is biased. A transistor responds to voltage on its input and output, and does not care how that voltage is developed."
Completely wrong.
The way a transistor works is GREATLY affected by the way it is biased. A transistor responds to CURRENT on its input.

No, you are wrong about that. And so is "Talking Electronics" if they aver that. Here is the reason why. Once a transistor is fabricated, nothing anyone can do externally will change its internal operation. It will operate the same way no matter what circuitry or voltages are attached to it. This principle is analogous to an op-amp. By attaching various components to the inputs and providing feedback from the output, you can make just about any electronic function you can imagine. But, now you have a circuit containing an op-amp, not just the op amp alone. The op-amp, by itself within the circuit, still acts like a dual high gain amplifier. So it is the op-amp circuit that provides the electronic function it is designed to do, not just the op-amp itself. In other words, the op-amp is not manufactured to be an inverting-amplifier or whatever else. The circuit itself is what makes a particular amplifier. Similarly, a transistor by itself is a transconductance amplifier, not a current amplifier. It can be made into a current amplifier
circuit by adding a lot of resistance in its base circuit or driving it with a current generator which, in effect, adds a lot of resistance to the base circuit. So a transistor by itself is not a current amplifier for the reason that it responds to its base voltage. The base current is a indicator of the collector current, but it does not control the collector current. The physics of the BJT prove that.
