What is the license for the Android SDK Platform Tools? How free are they?

android-sdk is in the Trisquel repo and appears to be under Apache 2.0,
with some additional data under CC-BY-SA.[1] Both are free licenses.

Replicant started maintaining their own version of the SDK because the binaries you download from Google come with a proprietary license:

But this stopped not because Google changed their mind but because of Debian:

"Would I be right in assuming that the android-sdk in the Trisquel repo is exactly the same as that found on the Android website?"

I would not say that. Because what you get with Trisquel comes with freedom, and without the proprietary terms like "you may not ... copy ... modify... adapt, redistribute, decompile, reverse engineer, disassemble, or create derivative works of the SDK..."
