I love it! It will make Bitcoin only stronger in the end. The less debt is used to enter this market, the less instability there will be in the long term.
Debt is exactly what makes the current financial system rotten to its core, and these financial institutions by doing this are helping everyone to keep Bitcoin's market clean from any sort of poisonous influence. I would advice all financial institutions to follow this path and to prohibit people from spending money they don't have. Let's keep that garbage out of Bitcoin. Thanks.
Another added benefit is that these actions once again show that financial institutions dictate people's lives, and obviously, an opposite reaction will follow.
