What's "artificial" shaping?

The average consumer ISP has an over subscription ratio of 70-to-1.

Unless you want to pay 70x as much for your "100mbit" connection, there are going to be times when packets get dropped.

Isn't it better to drop packets fairly among subscribers? No shaping would result in whoever is using the most dominating everyone else.

This basic principle is still neutral; you don't have to shape based on destination / content provider.

I should be able to turn it off, but I like that tmo throttles my video. I only get 2.5 gb, I don't need 1080p.

You can turn it off, but it removes the zero rating. Up to you either way.

I'm on the light package so I don't even get the zero rating.

What the ISP is doing isn't any different than what any private network could do. If YouTube can not handle that, Youtube is not playing well with standard network practices and is broken at a technical level.

Your ISP doing traffic shaping is a question of if they should, not a technical question.

In this case, that's what "broken" means. Not that there is something technically wrong, but that they are doing things that they shouldn't.
