There is no ethical excuse to ever inject code into a webpage.

...unless it's for adblocking...

Although I do that with a MITM proxy locally (and thus filters everything on my LAN), it would certainly lead to a very interesting situation if an ISP decided to do it...

I mean, the end-user who requested the page certainly has a right to voluntarily inject script into the page they requested as it is rendered in their own browser running on a machine they own connected to an upstream internet provider they pay for access? Nice try at false equivalence however.

What "false equivalence"? I was just pointing out an exception to the statement "There is no ethical excuse to ever inject code into a webpage".

It's false equivalence because you (and everyone else) knows that the case of an end user injecting script into a page on the receiving end of the connection is not the scenario under discussion, and is not the behavior that the rule implied by the earlier comment would be intended to prohibit. If the comment was tongue in cheek then I have misunderstood you and withdraw my objection :).
