This is a complex situation and I think awareness and upgrading our knowledge technically has become much more important. The hackers will not stop and bitcoin not being centralised becomes our responsibility to protect our wealth.
That's the job of hackers, always finding vulnerabilities to gain something for themselves.
So it is your responsibility as a user to take care of your funds. Third party sites has only limitations when it comes to security.
Be aware of what you are doing over the internet because you may be putting yourself at risk without knowing it.
