The people making decisions about what security products to buy can be very, very far removed from people who understand security. Windows defender, bless it, has changed it to a security built on ignorance.
Dismissive, brief statements like yours don't really help - they don't give me enough information to go research whether I should be recommending something else (including offering financial support to pay for subscriptions)
I know that Defender doesn't have the world's best detection rate but isn't it better than an expired copy of McAffee?
Should I be recommending EMET? Virtual Machines? Qubes OS?
