I have used both for many years and everything has worked absolutely as intended and I’ve had no problems.
Maybe not everyone knows what they’re doing completely? Maybe many people do something wrong by mistake but don’t know it? Or do, but they’re impatient? Or they get frustrated because they don’t want to fix their problem on their own and expect the product to be totally idiot-proof?
As an IT professional for several decades, I can attest this is the problem like 80% of the time.
