Some may considers D is Open Source. Some others may consider it's not. Many 
uses the following definition for Open Source.

I think it means that DMD (the reference implementation) would not be 
considered as Open Source.

The Open Source Definition is used by the Open Source Initiative to 
determine whether or not a software license can be considered open source.
The definition was based on the Debian Free Software Guidelines, written and 
adapted primarily by Bruce Perens. They are by no means definitive even as 
applied to software. Clause 3 is the primary legal difference between free 
software and open source software as such, free software is stricter in 
interpreting 3. Clauses 5 and 6 are not a condition of any major open 
content license regimes, which commonly do restrict types of uses and users; 
for instance, Creative Commons has open content licenses that explicitly 
forbid commercial use.

Introduction

  Open source doesn't just mean access to the source code.
  The distribution terms of open-source software must comply with the 
following criteria:
1. Free Redistribution

  The license shall not restrict any party from selling or giving away the 
software as a component of an aggregate software distribution containing 
programs from several different sources. The license shall not require a 
royalty or other fee for such sale.
2. Source Code

  The program must include source code, and must allow distribution in 
source code as well as compiled form. Where some form of a product is not 
distributed with source code, there must be a well-publicized means of 
obtaining the source code for no more than a reasonable reproduction cost 
preferably, downloading via the Internet without charge. The source code 
must be the preferred form in which a programmer would modify the program. 
Deliberately obfuscated source code is not allowed. Intermediate forms such 
as the output of a preprocessor or translator are not allowed.
3. Derived Works

  The license must allow modifications and derived works, and must allow 
them to be distributed under the same terms as the license of the original 
software.
4. Integrity of The Author's Source Code

  The license may restrict source-code from being distributed in modified 
form only if the license allows the distribution of "patch files" with the 
source code for the purpose of modifying the program at build time. The 
license must explicitly permit distribution of software built from modified 
source code. The license may require derived works to carry a different name 
or version number from the original software.
5. No Discrimination Against Persons or Groups

  The license must not discriminate against any person or group of persons.
6. No Discrimination Against Fields of Endeavor.

  The license must not restrict anyone from making use of the program in a 
specific field of endeavor. For example, it may not restrict the program 
from being used in a business, or from being used for genetic research.
7. Distribution of License

  The rights attached to the program must apply to all to whom the program 
is redistributed without the need for execution of an additional license by 
those parties.
8. License Must Not Be Specific to a Product

  The rights attached to the program must not depend on the program's being 
part of a particular software distribution. If the program is extracted from 
that distribution and used or distributed within the terms of the program's 
license, all parties to whom the program is redistributed should have the 
same rights as those that are granted in conjunction with the original 
software distribution.
9. License Must Not Restrict Other Software

  The license must not place restrictions on other software that is 
distributed along with the licensed software. For example, the license must 
not insist that all other programs distributed on the same medium must be 
open-source software.
10. License Must Be Technology-Neutral

  No provision of the license may be predicated on any individual technology 
or style of interface.
