Mono Project For the most time, I've been firmly in the largest camp when it comes to the Mono debate - the 'I don't care'-camp. With patent lawsuits being hotter than Lady Gaga right now, that changed. For good reason, so it seems; while firmly in the 'ZOMG-MICROSOFT-IS-T3H-EVILL!1!!ONE!'-camp, The-Source.com investigated the five most popular Mono applications, and the conclusion is clear: all of them implement a lot of namespaces which are not covered by Microsoft's community promise thing.

First, there is a legal binding patent grant from Sun/Oracle: http://java.sun.com/javase/6/jdk-6u21-doc-license.txt


This does not protect you at all as a developer using Java. It only protects you if you are implementing a functionality/interface-perfect clone of the JVM. It is unrelated to the languages in question and is of no use as an ordinary developer. Oracle has not promised not to sue users of Oracle JDK or OpenJDK. They have only promised not to sue implementors of Oracle SDK to the extent the implementation is fully correct.

As such you are no more safe using Java, Scala (on top of a JVM, similar to the status of C# in .NET/mono), python, ruby, perl, Open Object REXX and Commodore BASIC.

For what it's worth you are just as safe with mono as you are with gtkmm, QT or BeOS-api (Haiku and to some extent also Syllable). C++ or C are no safer in this regard. Languages are irrelevant. The promises are merely in regard to implementations of specific VMs and their associated Class Hierachies.

Some might say you are safer with mono and JVM-clones than with C and C++ frameworks because neither Microsoft nor Oracle have promised not to sue users of such frameworks ;) Considering the behaviour of Oracle their promise not to sue is worthless. Just look at Google.

It does protect me as a Java developer because the Java patent grant protects the OpenJDK which is under GPL + classpath exception. So there will always be a open source Java which cannot be sued by Oracle. This is just not true for Mono.

It only protects OpenJDK itself and derivatives that comply fully with the proprietary specification. Oracle can at any given time decide to cease development of OpenJDK and stick to the proprietary Oracle JDK. Then we have a dead OpenJDK that we cannot develop further without the risk of getting sued by Oracle. This is exactly the same risk mono is running.

The "risk" with mono is that U.S.-citizens might end in a situation where their chosen platform is killed off by Microsoft. The "risk" with Java (the VM, not the language) is that U.S.-citizens might end in a situation where their chosen platform is killed off by Oracle.

Of cours, the rest of us, living in countries without software patents couldn't care less. And I for one refuses to have my freedom limited just because you don't understand that to be free you must "violate" the software patents. Only through civil disobedience can you bring down the silly laws.

EDIT: Users of python, ruby, Open Object REXX and so on are running the same risks. They too can - in theory - be shut down at any given moment. It is highly unrealistic though, but so is the shutdown of mono and OpenJDK. In case Microsoft/Oracle try to do that, the development will simply carry on on European servers ;)
