Why do eBay charge 10% for postage that is a service which an element of that cost is insurance

I don't understand why eBay charge a percentage for postage in their sellers fee's. This is a service eBay don't supply and is normally supplied by the seller 

there is also a part of the postage that goes towards tracking which is eBay policy and yet they take a profit on that. 

jusy cancelled all my items for sale in protest, I know it won't make a difference but pure greed in my view

You've been an ebayer for almost 16 years... Ebay have been charging this fee for many of those years... You and every single seller were sent multiple emails and messages well in advance of this change all those years ago... And Ebay have been charging you for it every single month for all those years... Yet you've only just discovered this. I'm amazed.

Every other venue I sell on charges a selling fee based on the full invoice amount, including shipping. This is not something that's exclusive to Ebay.

I may have been on eBay for years but never noticed as I only sell very rarely. How can you charge for a service other people are providing. EBay don’t offer the postal service, I do

Your feedback suggests that you sell more than just very rarely, cannot believe how you have only just noticed fee on postage.

My feedback also suggests I buy a lot which I do. Why do you assume I knew, I didn’t had not idea but now I do. 1902elder assumptions are sometime misleading and wrong. Your wrong. If I need;to explain myself to you I will

One thing that is obvious though, is that you haven’t read your invoices for years!
