It is the responsibility of the judge to call out the times, but it's also the responsibility of the competitor to start the solve within 15 seconds. OP accidentally went over 15 seconds inspection because he thought he was being very smart and was trying to exploit a regulation loophole that does not in fact exist (*); if he'd just done the solve normally, he wouldn't have exceeded his inspection time limit.
If OP had a habit of waiting for the call-out to start, then that's fair, but according to the first post of this thread, that was not what happened. The second version of the story OP provided in a later post is from a very different perspective and is much less incriminating, which may or may not be an attempt to cover up guilt.
(*) The loophole exists insofar as you can do something like this and very likely not get caught (e.g. nobody would have known about this incident if OP didn't publicly admit it), but you're not supposed to do this. Nothing in the regulations permits you to do this. It's not difficult to cheat (unless you're a world-class cuber and have lots on eyeballs on you); we just trust people to not cheat.
Edit: Also, to be clear, the "unfair advantage" comes from the intention to take E1 only if the solve hadn't gone well.
