I am someone who does not agree with how the site handles such things so I have decided not to make any more money for them.
The only negative reviews I have ever gotten were do to people placing orders without contacting me first so therefore ordered in error and did not like what they were told. Not allowing sellers to cancel orders without the fear of negative impact puts all of the pressure on the sellers and no responsibility on the buyers. I don't agree with it.
As a professional there is no reason why I would tolerate this. In my professional career I am very careful with whom I work with or have business dealings with. On this platform they have removed all of those decisions completely offering zero assistance with the issue when they do pop up.
