What is the deal Managed.System.Drawing?

[jahav]

Hi,
there is a Managed.System.Drawing package that has official description

Fully managed replacement for System.Drawing.Common built using SixLabor's ImageSharp.

and is full of SixLabors classes.

When I look at the license(not declared on nuget):

The library is developed and maintained by IceTeaGroup (with the support of SixLabors) as part of the Wisej.NET ecosystem. It is freely available for non-commercial use and included without restriction when used within Wisej.NET applications.
Non-Commercial Use
You may use System.Drawing.Managed free of charge under the terms of the GNU General Public License (GPL) for:
...
Commercial Use
If you intend to use System.Drawing.Managed in a commercial product or service that does not use Wisej.NET, you must obtain a commercial license from IceTeaGroup.

the authors declare they have your support.

Is it a legitimate package made with your support, supply chain attack, or a package made without your support?

Yes. It’s legitimate. Wisej employed Six Labor’s to create the library.
