That's the startup's problem and not their users. It's too much work to reply to every email you get which you wish you didn't.

I realize it's hard but the onus is on the startup to get this right. In the process they'll piss off some users but that's the process.

True, but it wasn't too much work to find a HN thread about it and complain there.

Either be constructive or don't say anything. Both are good feedback for the startup. Being mean doesn't help anyone - the startup or the user.

While combataircraft's tone isn't the nicest, he's voicing exactly what he's unhappy about, giving the Filepicker.io guys the information they need to improve in the future.

Could it have been put in a friendlier tone? Sure, but I'd argue that his feedback is actually constructive.
