It's becomes piracy when you create a new distribution without ads... which you're doing with ad blockers.

That is not what distribution means.

I am allowed to splice up my personal copies of videos.

You are allowed to splice it up, when you have a legally acquired personal copy.

But in this case you don't have one in the first place.

		They are sending the data for me to watch. Legally able to watch and legally able to splice up are at the same level, as far as copyright is concerned. And I don't even need to make an extra copy to do the kind of live splicing an ad blocker does.

A data point is TiVo who are, apparently, still around and have a 'skip ads' button on recorded content.

		Still not a new distribution.
