So when did it become acceptable to leave tracking code turned on by default (opt out) in open source repos?
Are you finding this particular tracking code acceptable? Apparently not.
So there was never any coherent whole that could have found something unacceptable to begin with and in the end there are still disparate parts that continue to find it unacceptable.
I guess this is an obvious and tiresome answer, but I'm not sure what else you would expect anyone to say.
Just because I review code doesn't meant I accept or use it so your assumption is wrong.
There should be nothing tiresome about calling out for discussion of evolving trends in software or anything else.
If you see nothing negative about this practice then speak out constructively.
What I find tiresome is insisting that the use of some license or the other is a statement of values (your phrasing also implies that history clearly agrees with you, which I tend to find tiresome).
If the readme and other materials made repeated attempts to invoke some set of values and the source was contrary to that, fine you have a valid gripe, but the readme doesn't mention the license and the homepage ( http://google.github.io/flatbuffers/ ) keeps it to "It is available as open source under the Apache license, v2 (see LICENSE.txt)."
