Is a husband's jealousy over his wife, who communicates in writing with non-mahram men on Twitter about general topics without jesting, religiously justifiable?

There is no harm in a woman participating with non-mahram men in discussing legitimate issues in public forums, provided she adheres to the Islamic guidelines. Commendable jealousy is present in cases of suspicion. If the husband fears his wife's corruption through these means, such as private messages, he must prevent her; because he is commanded to protect her from causes of temptation, as Allah says: "O you who have believed, protect yourselves and your families from a Fire" (At-Tahrim: 6). And a man is commanded to teach his family, discipline them, and save them from the Fire, and he is responsible for his flock, as stated in the Hadith: "And a man is a guardian over his family and is responsible for his flock." And whoever cheats his flock, Allah will forbid Paradise for him.
