Introduction:
Stalin (famous Russian tyrant) is calling to chief of secret police: "Tomorrow you must execute 1000 people and paint Red Square in green color. Do you have any questions?"
Answer: "Mr.Stalin, why do you prefer a green color?"
Stalin: "It doesn't matter, but I like that you have asked about color only"
Resume: It doesn't matter, is new feedback rules fair or unfair. The most important thing is that EBAY requires to pay much more then before. They show you a sweet candy (15% off, if you have 4.8 rating) and present lower insertion fees (was 0.60, new 0.55 LOWER FEE!!!, but FVF was 5.25%, new 8.75% (why there is no mark of exclamation???).
Why did they choose DSR 4.8, nor 4.7 nor 4.9? They have statistic data how many PS have rate above 4.8 at the moment and they plan to pay back, let's say 1% of income. If more PS will get rate above 4.8 in future, they increase tier to 4.9 and ....
THEY WILL NOT PAY BACK MORE THEN THEY PLANNED.
EBAY.COM is doing business, EBAY doesn't care about fair rules, buyers and sellers (especially from Canada, I suppose EBAY.CA turnover is 1-2% of EBAY.COM.)
Well .. count your profit-loss balance after Feb 20 and make your decision: stay or leave, it doesn't matter what DSR tier is fair, EBAY has decided: "You must pay more!".
