1 I agree HF20 has been a mess.
2 The RC calculations are causing a lot of trouble. I thought RC was similar to bandwidth, which was not good for newbies. Otherwise, bandwidth didn't affect me.
Now, it seems this RC stuff is designed to limit activity.

3 If this caused trouble for blocktrades, due to high activity, then it will affect Bittrex and Binance also, which explains why they are still suspended.
4 if 3 is correct, then HF20 was designed to limit and suspend the exchanges. This doesn't make sense.
