Personally I think it is an excellent approach to protect all of us regular sellers,.  Looking at your sales history you will be treated as a new seller,  and you did tick the I agree with the Terms and Conditions button,  which I guess you read.

And as Dave said,  they cant invest it on the short term money market.

Commissions seem reasonable as well,   maybe you should try setting up a sales platform and see what it costs you.
