Below is my opinon as an Eclipse community member (not speaking on behalf of the foundation nor my employer)
I recognize the wording CodeEnvy or rather the Eclipse Che project is bold and for some maybe even directly threatining - but I do not believe the foundation as such should restrict a specific projects ability to market it self as long as it is not directly deceiving nor outright lying.
And Che stating it is a next generation Eclipse IDE is not false, neither was it when the similar wording was used by the press when Eclipse Orion was starting off.
If we (the desktop Eclipse IDE community) want desktop Eclipse IDE to survive and grow we should not be scared about words stated by other communities inside or outside Eclipse.
We should be encouraged to show show the desktop Eclipse IDE also can grow and not stay stagnated as it have done for a while now.
This really is nothing new and sure we can "blame" IBM and other companies for retracting its original people investement into desktop Eclipse IDE - but that are those companies choice, not the Foundation. We'll either need to replace those people or change how we do things. I've helped where I can from my role in Red Hat but just like IBM couldn't pull it of forever alone, neither can Red Hat.
This is why I've done what I can and will continue to do in future on the desktop Eclipse platform features, and I encourage everyone to do what you can too. Talk to your companies, talk to your contributors and encourage collaboration and more contributions to grow the desktop Eclipse IDE.
And in that, we cannot ignore there are other markets where a cloud IDE like Eclipse Che has its major advantages over desktop Eclipse - just like desktop Eclipse IDE has advantages over cloud IDE's.
We are entering a world where there no longer will be a "single" IDE,
the community both inside and outside Eclipse foundation have spoken
stating that one IDE does not fit all. Some don't even want a full IDE, just a fancy editor.
As a long time contributor to desktop Eclipse IDE and other tools out there, I understand that there are limited number of people who will actually be able to contribute to a single platform. Thus the "multi-IDE" world do scare me, mainly since it means more work for me and my team ;/
Backing the language service protocol is my way to try and build the technical bridges between these multiple IDE's - if it works, all will grow. If not, one will grow stronger faster and win.
This is how opensource works. This is how (almost) anything works and evolves.
