All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.
The matter is easier than to make you shocked or worried.
If you had carefully read what we mentioned at the end of the fatwa, then the matter would have been clear to you. The examples that were mentioned are related to the customs that were common at that time, and these customs vary from time to time, from place to place, and from situation to situation.
The teachings of Islam are very clear about the commandment in regard to having good marital relations with the wife; Allah says (what means): {And live with them in kindness.} [Quran 4:19]
Also, it is forbidden to abuse them or harm them, and Islam threatened the husbands who transgress against their wives; Allah says (what means): {But if they obey you [once more], seek no means against them. Indeed, Allah is ever Exalted and Grand.} [Quran 4:34]
Ibn Katheer said, βThe saying of Allah {Indeed, Allah is ever Exalted and Grand} is a warning to men, meaning that if they transgress against women without justification, then Allah, The Exalted and Grand, is their (women's) Protector, and He will exact revenge on those who transgress against women and deal with them unjustly.β
Indeed, we have already clarified in the fatwa which you referred to how the Prophet used to serve his wives. The person who helps his wife in her household chores is the generous one who has a good character, whereas the one who refuses to help her is the wicked one who has a bad character.
Finally, it should be noted that it is better for a Muslim to ask about matters that lead to doing good deeds and not preoccupy himself with questions about misconceptions, which are endless. The bad actions of the people are endless, and the teachings of Islam regarding the good treatment of the wife and the like remain clear, and its followers are judged according to their actions.
It is not Islam that is accused if its followers violate its teachings, but the Muslim fulfills his duty of advising his fellow Muslim so that the latter follows the truth, because religion is sincere advice.

Allah knows best.
