They are giving these assets out for free, and they most likely use Macs internally.

If you want them for Linux, feel free to provide your own to the community.

It doesn't look like this is allowed.

I can't. I neither have the resources nor the ability. However, locking it to the Mac ecosystem eliminates possibilities for third world countries (like India and China) which are using Linux right from schools.

I believe the appropriate idiom here is: "Don't look a gift horse in the mouth".

> "Don't look a gift horse in the mouth"

The winners apparently write both the history and the idioms. The Trojans would have done well to look a gift horse in the mouth.

Looking at a real horse's teeth shows how worn down they are over age. Looking at a horses teeth is to check its age.

The idiom could be modernized to: 'dont check the odometer of a gift car'

[Menge]

Yes, and the assumption is that a horse is worth between $0 and some number so there is never a reason to refuse a gift horse.

In the case of other "gifts" the value can be negative. The trojan horse, software, and blankets from Lord Jeffery Amherst all need careful examination.
