LifeLock differences with Locks and Freezes

Was wondering if anyone knows why LifeLock treats TransUnion a bit differently than Equifax and Experian?  LifeLock really pushes a person to lock their Transunion account instead of freezing even though freezing is more secure.  With Equifax and Experian, LifeLock does the right thing, in my opinion, and focuses on freezing.  Why the difference with TransUnion?

Thanks 

TransUnion: $29.95 per month

Thanks, bjm_, but I already know the difference between a freeze and a lock, I'm just wondering why LifeLock treats the TransUnion lock and freeze differently from the Experian and Equifax lock and freeze.

Thanks again,

 Why the difference with TransUnion?

 

A credit freeze and a credit lock are two ways to protect your credit reports from being used by scammers to open new accounts.

You may see the terms “credit freeze” and “credit lock” used interchangeably, and they do offer similar protections. The three major credit reporting bureaus — Equifax, Experian and TransUnion —sometimes promote their credit lock services, which can carry a monthly fee, alongside their credit freeze options, which are free. A key difference is that it can be faster to unlock a credit lock than to “thaw” a credit freeze. But a freeze may afford legal protections that a lock doesn't.
