Modifying client code (especially with an addon you do not control) and then complaining to the original code owner when functionality stop working is wrong.

Analytics and ads are annoying, I get it. However if you use an automated script to clear them out, be aware that some things might brake.

If Ublock Origin devs think they need to replace GA with a dummy to stop tracking they should've put a copy of the original interface with empty functions into it so the flow doesn't throw exceptions when the app tries to use it thinking everything's fine. Those scripts are publicly available and aren't a secret.
