The ad blocker is probably trying to do the right thing for their users, to. Too many websites check that GA is loaded, if it is, then do stuff with it, if it's not, then redirect to a "Please disable your ad-blocker" page.

I think the key point is that the only way to do this right is to have a quirks list and both implementations, and pick the implementation based on that list.
