The most important concern in the minds of social media users is the protection of their privacy. Accordingly, as per the privacy policy released to customers, most social media companies use the latest 256-bit encryption techniques to transmit and store user data. However, recent tests done by several security companies show that 128-bit encryption is sufficient for all practical purposes. Hence, if data security is the only objective, then by switching to the older and cheaper 128-bit encryption, media companies can increase their overall profits without compromising on the security of user data.

Which of the following, if true, argues against the suggested change in the encryption techniques?

(A) Surveys have shown that customers are also concerned about whether paid accounts at social media websites offer better features than do free accounts.

(B) Most smartphones and tablets still use 128-bit encryption techniques and do not support the 256-bit versions.

(C) Although the companies will realize net cost benefits by switching to the 128-bit encryption technique, the companies will have to bear the initial cost of installing the new technique.

(D) Most consumers do not read the privacy policy of the social media network they are active on.

(E) Customer surveys indicate that most users would switch their social networks in case of any perceived downgrade of security features.
