Answer:
All communication way back used to be wiretapped, but now companies have been able to encrypt their data for protection of their information against wiretapping.
Companies like silicon valley has taken the bold step in securing their data from been hacked.
The back door is risky because if a person or people exposes their information to others, their information will be at risk because of hackers who might exploit their privacy or sensitive documents.

Explanation:
Solution
Before now all communication used to be wiretapped. presently, companies are encrypting data , for the purpose of this data to not be easily wiretapped.
Silicon valley companies have secured their devices through encryption unlike other companies. what this implies is that it will be tough for police to arrest criminals, but the normal or average people will have capacity to communicate or interact much better.
The back door method is risky because, presently in today's world there are people that are specialist in hacking, so if no backdoor exist, then there will be no room for anyone to hack into someone's phone.
It is considered a risk if your phone is exposed to others to easily access your private information.
I don't like the idea for devices should be wiretapped, this is because people need their privacy, they can't have that when their phones are wiretapped.
In general it is illegal and not right.
