[License-review] Amazon FreeRTOS - new license or not?

[Kate Stewart]

Hi,
    Today Amazon relicensed FreeRTOS from GPLv2 to "MIT"[1].

However they didn't quite use the standard OSI MIT text. [2] instead they
used:

FreeRTOS Kernel V10.0.0+ * Copyright (C) 2017 Amazon.com, Inc. or its
affiliates.  All Rights Reserved.+ *+ * Permission is hereby granted,
free of charge, to any person obtaining a copy of+ * this software and

and/or sell copies of+ * the Software, and to permit persons to whom
the Software is furnished to do so,+ * subject to the following
conditions:+ *+ * The above copyright notice and this permission

the Software. If you wish to use our Amazon+ * FreeRTOS name, please

SOFTWARE.



The phrase "If you wish to use our Amazon FreeRTOS name, please do so in a
fair use way that does not cause confusion".
is an extra condition.

For those creating license scanners,  should the change be considered
substantive enough to warrant a new license,
or should it be recognized as  OSI's "MIT"?

Since FreeRTOS is so pervasive in the embedded world,  we'll likely need to
address this in SPDX license list if it
warrants a new license identifier.

Thoughts?
