Incompetent management is always a problem but in remote teams it's even worse. With onsite teams the manager can at least track attendance and can generally see if people are doing some work. With remote teams your only measure is the output of people and that's very hard to judge if you are not competent.

I think you also need to hire differently for remote. People need to be self-motivated and self-sufficient.

It's not a 100% difference, but there are different dynamics to almost constant face to face communication. Some management styles would have a problem. Similarly, a remote manager might have their work cut out for them moving into a more traditional in-the-office company. But there are different workflows, different subtle problems to notice, etc.
