Bend it how you will, break it to fit how you must, but if that's how you have to make it fit your world view, then nothing I can say to make you change. The summary of your argument is: These headphones are like these other headphones for hundreds of dollars less, so just suck it up and buy them because they are worth it.
To address your points and my points...
Do I want to shame them? Yes.
Do I want to make them do what I want? Yes.
Does landed stock, magically become more expensive? Maybe, but that's for the company to sort.
Did they say it had anything to do with stock? No, they actually said it was a planned increase.
Did they decide to push the price increase formula? Yes they did, on other MD made drops, drop ended, when drop returned the price was higher. This time they lifted the price during the drop.
Did they expect pushback? Yes, they did it Saturday morning and the first official acknowledgement was Sunday by their marketing goon on Reddit.
Could they have avoided this? Certainly, but they want to talk about improving customer relations and act like that. The hypocrisy is amazing.
Could they have bought me off? Certainly, I'm human and I want the HD6XX, I would have told everyone though.
Will I get a pair of HD6XX? Likely, but they've made sure I'll end up with a pre increase used pair or a set of real HD6*0s.
I'm not sure about you, but I'm not buying anything right now from here and I won't be for some time. I could swear off the place, but maybe they get better, shouldn't I give them that chance?
Commerce is and will always be a two way street, between seller and buyer. I'm an advocate for the old saying it's best when both walk away happy.
I'm just here to say my bit, share my headaches, and hopefully through my words and actions, make Massdrop change their future actions for the better.
