"insbesondere David Brabens ehemaliger Kollege und Elite-Koentwickler Ian Bell kritisierte auf Kickstarter die späte Ankündigung kostenpflichtiger, aber spielverändernder Inhalte als unprofessionell"
For those of you who cannot read German, translation is as follows:
"in particular, David Braben's former colleague and Elite's co-developer Ian Bell critisized [in Kickstarter comments] the delayed announcement of non-free, yet game-changing content, citing this move as 'unprofessional'".
The comment the article links to has since been deleted; looks like the gentlemen are trying to quell it, probably on both sides. Still, the fact remains.
