my days of fighting for ui usability have ended, so nowadays i sometimes simply squint my eyes. works but can have side effects!
the only reason you have to state that the 'delay' is a response to the open letter is that frontier stated so, which is as dubious as an assurance as can be. there is a lot of evidence though pointing to other factors (which have been discussed at length so i won't re-iterate).
even if it were true, what the openletterers where asking for was quality, period. it means doing work professionally. a delay is not necessarily a requirement for that (although it can be fairly accepted as a necessity when stuff has gone too stale, which is the case). (they also naively asked for 'beta' which was a gross miscalculation on their part).
least but not last ... frontier has ostensibly not changed their ways (sloppy beta, untested code in release, etc), which is what the delay was supposed to be for.
now, you may agree with yamiks or not, i don't share much of his opinion myself, but the sequence of events i just described can hardly be disputed. in that scenario the whole "players don't know what they want and will moan anyway", while enclosing a fundamental and universal truth is completely uncalled for and is simply an ad-hominem (at a whole diffuse and abstract collective). i'll grant you that yamiks' poor choice of video title had it coming ...
