Kinda baffled at the view of "Chabad" as a corporate entity, almost like a Starbucks chain. These are individuals. They have individual jobs and goals and reasons for being where they are and doing what they do. The expectation of uniform perfection is one that we would not dare try to place on any other group of Jews who happen to follow the same mesorah. Are some shluchim rude? Sure. Do some display an unimaginable sense of bitul? Yes. They are individual people, with independent personalities.
FWIW, I read the tweets as being written with a tone of bemusement. The campus shliach who's lucky to get 40 people show up at his biggest events (and 85% of them are girls) is wondering what made anyone think he'd have daily minyanim. He's in the middle of nowhere and doesn't run a shul. He runs a student center. The shliach to a 238 sq. mi. island with a total population of 165k is bemused that someone who researched the place enough to want to go there thinks there may be restaurants there when he has to import shelf stable CY milk from France. There's a certain amount of common sense that's expected, and when the lack of it is so prevalent, it begs asking. You want to know why on Twitter? I agree, probably not the best place. But I also don't live in total isolation, where social media is a huge part of my interactions with like-minded people, so I can't exactly judge.
