If you think Apple is intentionally making it harder for law enforcement to gain access to an iPhone, you don’t understand Apple.
Apple’s decision here is to protect the customer data, any way possible. If they see a possible vulnerability, they fix it. If it happens to interfere with the vulnerability law enforcement was using to gain access, then it just does. Keyword here is vulnerability, as they do not have secret access but are exploiting a bug in the software.
If Apple was to keep this vulnerability in place, just for law enforcement, then they are designing a product that has the potential to be hacked by other sources and puts honest people at risk. Creating a backdoor hurts us all.
I understand helping law enforcement is important but not at the expense of personal data being put at risk – which it will be if this vulnerability is left open.
