In general, obtaining access to your account at some service providers requires you to defraud, social engineer or hack that service. To be able to do that legally, you need permission from the service provider, permission of the owner of the account isn't sufficient.

So any company claiming to provide such service is either not doing so legally or (more likely) limiting their activities to various passive approaches and not attempting to actually pentest/social engineer access to your accounts in ways like an actual attacker would; so they're implying that they provide a better, more serious service than they actually do.
