Does もらう express gratitude?


I've come across the following:

> ## もらう (morau)
>
> This is the last word we’re going to review. もらう (morau) means to receive or
> to get. This word has a nuance that you’re feeling grateful of what you’ve
> received. So you cannot use it for something that have negative nuance or
> about something that you don’t feel grateful about.

Is this true? I can't find a reputable source which states the above. My book
doesn't seem to mention this "nuance".




I don't think this is true.

We do use "もらう" when we received something unwanted.

Like _変なモノもらっちゃった(I received something weird.)_ , or (a little bit tricky use)
_風邪もらってきちゃったみたい(I think I've caught a cold.)_.

It's either the author of this article has misunderstood something, or he/she
doesn't fully understand the language.
