New wording: "This source code is licensed under BOTH the GPLv2 (found in the LICENSE file in the root directory of this source tree. An additional grant COPYING file in the root directory) and Apache 2.0 License" (emphasis on "BOTH" mine).
-> IANAL, nor a native english speaker, but shouldn't it be "EITHER" instead of "BOTH" ?
No it should be BOTH. You can use it under the terms of either, but it is licensed under both. If it was licensed under EITHER the obvious follow up is - Well which is it actually licensed under?
IANAL either but I am a native UK English speaker.
"This source code is licensed [to you] under EITHER" whereas "Th[e] source is licensed under BOTH". The "this" hints at a genitive that's not there but still feels there. (Linguistics class was a long time ago btw.)
