I don't think a 'boycott' per se would work. I don't really know how it even could, since the devs clearly don't really care if we watch cutscenes or not as long as we still pay each month.
But I think we can find some closure in knowing that since the drop of DT in summer, the reputation of the MSQ (which was once called one of the best if not THE best MMO story there is) has suffered a lot. Which should not be a good thing for the dev team and ring some alarm bells.
Unfortunately, as they don't want or can change course right now...this is probably gonna get much worse over time.
Well...you reap what you sow.
