IMO, this isn't about whether torque wrenches have a place, or whether people should use them. In some cases they should, though in most cases a skilled mechanic can use hand feel and experience to judge properly fastener torque.
My problem with torque wrenches is how they're used. For torque wrenches to have any value, the published specs must be meaningful, and the wrench must be used properly. Unfortunately in many cases one or both of these conditions aren't met.
The other problem is that in many aspects of bicycle maintenance, as in many aspects of modern life, there's a tendency to reduce things to a step by step, follow the numbers approach, discounting the value of the experience and judgement that a professional brings to a task. That means that unqualified, mechanics will use torque wrenches o blindly tighten a bolt and blame others when it doesn't work out. All to often we hear, "I tightened with a torque wrench and it broke, it must be defective." and that's why I'm not a fan.
IMO, most applications don't require a torque wrench, but might benefit if one is used. However a torque wrench or any tool is not a substitute for user skill.
