What is the opinion of one who rules that a person's methodology is not Salafi because he adopted a means of da'wah that some do not permit?

Question:
He says: Honorable Shaykh, may Allah grant you success, is it correct to determine a person's methodology based on a matter of scholarly disagreement regarding the means of da'wah? It is said that these people are not Salafis, but they are judged as such because they adopt means of da'wah that some scholars do not approve of. Is this a correct classification and division?

Answer:
There is a difference between the means of da'wah and the methodology of da'wah. The methodology of da'wah is prescribed (taqdiri), and it is what the Messenger (peace and blessings be upon him) did in his da'wah. . . This is the methodology of da'wah; it is prescribed and is taken from the Qur'an and the Sunnah.
As for the means of da'wah, these are renewed. For example, the microphone: I am speaking now and everyone around the mosque hears me. Did this exist before? Is this a means of da'wah or not?
It is a means of da'wah. I take a car and go here, or a plane. Did this exist before? I go to preach in such-and-such a mosque, or I speak, or I deliver a lecture. These are among the means of da'wah that Allah has permitted us to use. Radio and the press are among the means of da'wah. They did not exist before; they are not prescribed (taqdiri), but rather they are adopted based on what is beneficial in each age according to its circumstances. So there is a difference between the means of da'wah and the methodology of da'wah. The methodology of da'wah is prescribed, and it is not permissible to add to it anything that is not from the Sunnah of the Messenger (peace and blessings be upon him). As for the means of da'wah, they are renewed in each age according to its circumstances. Yes, otherwise we would not use the microphone now, nor the radio, nor use them for da'wah, nor use newspapers and magazines, because they did not exist before. Yes.
