Are Coinbase and GDAX exchanges scamming users for not giving them BCC (bitcoin cash)?

I use Coinbase since one month and have no complaints (except that their fees are pretty high, and their BTC price is always on the high end). Anyway, it is the easiest system to buy BTC using my bank account or debit/credit cards.

However, now that they announced they will not support BCC and won't give their clients the equivalent BCC for the BTC their client hold I am having a change of heart. What this means is that if you have 1 BTC on Coinbase, After August 1st, you will still own 1 BTC. However, on other exchanges, or even if you control your own BTC, after the upcoming fork and the release fo BCC, you will own 1 BTC + 1 BCC.

Clearly, Coinbase decision is horrible. Will they take the new BCC for themselves since they control the private keys for the bitcoins they hold?

Another crazy thing I noticed, Coinbase and CDAX (which I never used) have the exact same copy of the announcement, are they somehow related? Read both announcements yourself and judge:

GDAX announcement:

Both Coinbase and GDAX claim that "it is hard to predict how long the alternative version of bitcoin will survive and if this will have future market value." this is BS, look that the expected future value of bitcoin cash on coinmarketcap:

This is some crazy shit going on, IMHO
