** Too many errors and misleading claims to even know where to start.

Push pull output stages can operate in class A, B or AB - the latter being
by far the most common.

Each output device amplifies an input signal of one polarity ONLY if the
load is resistive.

The efficiency of an ideal class B output stage varies from zero to 78.5% at
full power.

The efficiency of an ideal class A output stage varies from zero to 50% at
full power.

So both are horribly inefficient at low power.

Assuming you consider it a voltage amplifier. As a current amplifier
or a transconductance amplifier the one polarity restriction would
still apply (and in fact must apply for class B unless the individual
devices can somehow carry a current flow in the reverse direction).

Not having read the article, I'll assume the rest of your points are
valid.

** Input "signals" are normally voltages and the OP's schem makes this the
case too.

** How nice of you.

Try learning to read stuff .
