Salam alaikum
Perhaps it could have been that the slave girl would have found it harder to find means of living and that the uncle of Maimuna bint al Harith may have been a pious man who took good care of his slaves. He may also have been old/disabled man who needs care.
Allah knows best.
And, brother: It's Islamophobes who need to be reftuted not the hadeeth.
That's an excellent video on islam and slavery:

Wa alaikum salam brother Sama,
I not sure exactly why the prophet said that it would be a better reward to give an uncle instead of emancipating her, but there are many other hadith are contradicted about this.
Narrated Mu'awiyah b. al-Hakam al-Sulami:
I said: Messenger of Allah, I have a slave girl whom I slapped. This grieved the Messenger of Allah (ﷺ). I said to him: Should I not emancipate her? He said: Bring her to me. He said: Then I brought her. He asked: Where is Allah ? She replied: In the heaven. He said: Who am I ? She replied: You are the Messenger of Allah. He said: Emancipate her, she is a believer.
Abu Dawud Book 21, Hadith 3276
So, the Prophet emancipated her instead of giving to an uncle.
Another one:
Ibn Umar reported that 'A'isha decided to buy a slave-girl and then set her free, but her masters said:
We are prepared to sell her to you on the condition that her right of inheritance would vest with you. She (Hadrat A'isha) made a mention of that to Allah's Messenger (ﷺ) whereupon he said: This should not stand in your way. The right of inheritance vests in one who emancipates.
Sahih Muslim Book 9, Hadith 3584
Abu Dawud reported the Apostle of Allaah(ﷺ) as saying “Anyone who sets his slave girl free and then marries her, will have a double reward.”
Abu Dawud Book 11, Hadith 2048
Double Reward?! Wait, I'm confused. The prophet said it's better a reward to give a slave girl to an uncle. Hmmmmmmm?
Let's move on!
Anas said “Captives were gathered at Khaibar. Dihyah came out and said “Apostle of Allaah(ﷺ) give me a slave girl from the captives.” He said “Go and take a slave girl. He took Safiyyah daughter of Huyayy. A man then came to the Prophet (ﷺ) and said “You gave Safiyyah daughter of Huyayy, chief lady of Quraizah and Al Nadir to Dihyah? This is according to the version of Ya’qub. Then the agreed version goes “she is worthy of you.” He said “call him along with her. When the Prophet (ﷺ) looked at her, he said to him “take another slave girl from the captives. The Prophet (ﷺ) then set her free and married her.
Abu Dawud Book 19, Hadith 2992
Hilal b. Yasaf reported that a person got angry and slapped his slave-girl. Thereupon Suwaid b. Muqarrin said to him:
You could find no other part (to slap) but the prominent part of her face. See I was one of the seven sons of Muqarrin, and we had but only one slave-girl. The youngest of us slapped her, and Allah's Messenger (ﷺ) commanded us to set her free.
Sahih Muslim Book 15, Hadith 4082
I think that is enough evidence that Muhammad (phub) clearly emancipated slave girls instead of giving to an uncle.
What the holy Quran really says about slavery?
(002:177) Righteousness is not that you turn your faces toward the east or the west, but [true] righteousness is [in] one who believes in Allah , the Last Day, the angels, the Book, and the prophets and gives wealth, in spite of love for it, to relatives, orphans, the needy, the traveler, those who ask [for help], and for freeing slaves; [and who] establishes prayer and gives zakah; [those who] fulfill their promise when they promise; and [those who] are patient in poverty and hardship and during battle. Those are the ones who have been true, and it is those who are the righteous.
So, these 2 Hadith that I mentioned early are either fabricated or abrogated.
Do you agree this?
