Did some more research and Netflix did remove their "Basic" plan when they added the cheaper ad-supported tier. They also raised the prices of their other plans, but those increases were consistent historically, so I'm not convinced the addition of an ad-supported tier caused them.
Isn't this exactly what Netflix is trying to do with their paid subscribers?
Netflix didn't start with ads, and the ads don't affect pre-existing subscription tiers.
… other than the fact that they cost more to 'make room for' the ad-supported service at and near the former price points.

For what it's worth, Facebook didn't have ads way back in the day
