I think it was a bit aggressive, though i sort of understand it: one of the most common (if not the most common) complains after a UX change in any semi-popular program is that the change was negative for some people's experience and i think everyone who has used computers for a while has experienced at least once what they perceived as unnecessary UX degradation of one of their favorite programs.
So whenever the topic of some program changing their UI (regardless of reasons) comes up, a kneejerk reaction that goes fully towards the negative side of possibilities is expected. The more time people invest in a program, the more painful it becomes when they feel that their investment becomes worthless.
(EDIT: FWIW personally i do not make any weird use of VLC, so as long as it keeps having the common minimal slider, play, pause, etc UI i doubt i'll have any problems with it :-P)
