If you search this archive for security, I believe roc and/or John Daggett
explained some of them.

Not sure I understand what broke: did Firefox support fonts cross-domain 
before it implemented SOR ?

> Short term?!?!?!?! 
Yes. Until font code is hardened, you will have more exposure to 
vulnerabilities. I don't expect that to last forever. Although
I expect it to take longer than I think :)

Partially, yes. Cross-browser incompatibility and bandwidth costs
were other factors.

Font licenses are outside the scope of this WG. But technical solutions
that collide head-on with general licensing restrictions common across
the vast majority of EULAs are not that interesting. We aim to expand
choice, not reduce it.

It certainly is. But it is also conceivable that number of licenses - and 
fonts - that are not violated by this recommendation is far higher.

Why is it more problematic ? Are PNG, audio, video and other data format 
compressions problematic ?

Yes.
