So, there is terminology confusion because, these days, many people distinguish transit from peering without precise understanding on the peering situations.
Paid peering with a backbone provider will get you routes from their paying customers but not from their peers.
That argument may be applicable to the simplest cases of, so called, peering between leaf ISPs and transit peering (here, "transit peering" seems to be a proper terminology accepted by most) between leaf ISPs and upper level ISPs. But, with settlement free peering between tier 1 ISPs, tier 2 ISPs having transit/paid peering with a tier 1 ISP will receive routes from peers of the tier 1 ISP. There is transit traffic exchanged between tier 1 ISPs over settlement free peering. So, I don't think distinguishing transit from peering meaningful for precise discussions.
I do not want Netflix to pay me.
You are so generous.
Let me tell you the point. Large ISP can exploit their domination of the marked to double dip, which means they want to be paid twice. That happens to be not neutral and is a way to make the customer pay a hidden fee. For smaller ISPs it works the other way around. An evil CDN could attempt to charge us, the small ISP. I am happy that is not happening.
Because of natural monopoly and PON, most access/retail ISPs enjoy their domination in their own area regardless of their sizes. Masataka Ohta
