Isn't it ironic how the majority of threads on this forum currently discuss the abuse of power of government officials and the excessive violence of countless law enforcement agencies, while this thread abounds in commenters conspicuously ignorant of the problem?
Bribing the software engineers of an independent private business behind the owner's back, and/or showing up without announcement at private residences of major stake-holders is "arm-twisting" for all intents and purposes. Admittedly it's more subtle than the typical approach the Russian or Chinese governments would follow, yet the essence is the same. In rare cases, where bribery and coercion fail, there is the institution of FISA courts in the US and the lack of control over secret services in other countries.
The potential of a private business to say "okay we do it for money" is exactly the risk at hand and the reason for more than a handful of "accidental" security breaches in the recent past.
Where is this so-called "arm-twisting" ??
