It is not true. The non-inverting summing amplifier is used all the time. It is an excellent Analog Signal Processing circuit. As an example, the bipolar to unipolar converter can be designed with a non-inverting summing amplifier.

What is the use of operational amplifiers in circuits?
An operational amplifier is typically used where it is desirable to control a voltage over a wide range of levels; i.e., in analog mode as opposed to the on-off limits of a digital signal. An operational amplifier in simplest form will have a non-inverting and an inverting input terminal and an output terminal, each of which are analog in function. The output terminal will tie into external circuit components that eventually connect back to the inverting terminal. The key to its performance is that when a change is made to the voltage on the non-inverting input terminal, the output of the amplifier will change in voltage level, whether increasing or decreasing, to the level that causes the voltage appearing at the inverting terminal to equal that of the non-inverting terminal. In that way the output voltage is a predictible value that is useful for automatically controlling a flow valve or other device. Of course, it can also be used to just to act as a signal conditioner for sensors, audio devices and countless other applications.

Why non inverting amplifier op amp used in circuit?
To increase the current drive capability of a previous stage (with gain =1). To preserve the phase of the signal when used in summing circuits etc.
What is invertion?
An inverting amplifier is one where the output is an inverted function of the input. The Class A transistor amplifier, also known as common-emitter, is inverting. As you increase the voltage on the base, the output voltage on the collector decreases. The operational amplifier has an inverting and a non-inverting input. In typical bridge mode, the output is inverted with respect to the (inverting) input, and the non-inverting input is used to reject common-mode input signals by moving the virtual ground point as needed.
How op-amp can be used as adder?
An operational amplifier (op-amp) can be configured as an adder using a summing amplifier circuit. In this configuration, multiple input voltages are fed into the inverting terminal through resistors. The op-amp produces an output voltage that is proportional to the negative sum of the input voltages, scaled by the resistor values. By using feedback and appropriate resistor ratios, the circuit can be designed to add the input voltages with desired gain or weighting.

What does a comparator do in electronics?
A comparator is an operational amplifier used without a feedback circuit. The output of the comparator will be high when the voltage of the non-inverting input is below the inverting input, and low when the inverting is above the non-inverting input. The output is undefined - i.e. can by anything - when the voltages are equal.
What is an inverse amplifier?
An inverse amplifier, commonly known as an inverting amplifier, is a type of operational amplifier (op-amp) configuration that produces an output voltage that is inversely proportional to the input voltage. This means that if the input voltage increases, the output voltage decreases, and vice versa. The gain of the inverting amplifier is determined by the ratio of two resistors in the feedback and input paths. It is widely used in various applications including signal processing and analog computing.

Reason use an op amp in a closed loop control system?
Differential Amplifier or Summing Amplifier are usually used in a closed loop control system. The error signal will be the DIFFERENCE between the setpoint value and feedback value for Differential Amplifier. Whereas for Summing Amplifier, the error signal will be the difference between the setpoint value and feedback value only if one of the value is inverted in polarity. Another reason Op Amp is used: amplify the error signal as error signals are usually very small. Hope this helps.
What is the origin of the name operational amplifier?
In the old days, Op Amps were used in analog computers to perform mathematical 'operations', such as summing, differentiation, integration etc. Hence the name.
