One huge problem with Xara's "open source" move was they kept a critical element closed source:
"Xara and the volunteer developer community disagreed from almost the very beginning about a crucial issue: the company's decision to keep the application's core rendering library CDraw closed source. The developers said time and time again that a half-open, half-closed application was a dealbreaker."[1]

If you do any such thing you can't expect open source to work for you.
