The comment you're responding to explicitly stated why they don't want to engage with this content. To try answering your question though, I'm going to guess it's because Morocco has been buying US arms for a lot longer than Ukraine has. In the title, "has received" is incredibly misleading, it makes it seem like the US is giving tanks to Morocco, but they're buying them.

I don't care how they feel about the source. I think we're all grown-ups here and are capable of seeing through any propaganda the source may have added to the facts. I'm here to discuss the factual content of the article, which is rather interesting. I haven't been following the drama of northwestern Africa's territorial disputes.
Don't guess, because you're just wrong. 1st sentence. "The received tanks were immediately deployed to the southern part of the country, specifically to the disputed Western Sahara region." Some other commentors added more relevant info, so nice of them.
"has received" is indeed misleading, if you're in high school. No one receives weapons for free, not even Ukraine or Israel. Obviously Morocco paid for them.
