This is a very single-user-centric view. Some of us have Macs with many hundreds of users.

And so .. It is too invasive of my .bashrc/.profile that I have to use it to disable spy activity. I'd rather brew just have its own flag somewhere that says "Don't ever send analytics, ever, for any user on this system.."

Maybe put it in /etc/bashrc ?

Maybe not have to pollute files just to not be spied on, hmm.. I'm sure brew has the cleverness to keep this configuration option in its own tree.
