The thing is, you can push people like this, but then expect an appropriate backlash. Expecting people to replace all their peripherals (where many may simply not be available in USB-C) or to carry a bag load of dongles will only push them closer to switching platforms. If a Windows laptop can do everything they need to do, doesn’t have these boneheaded hw decision and is cheaper to boot, people will start switching. Professionals are not sheep and the discontent is huge already - people likely won’t switch over a USB-C only ports, but it could well be the straw the broke the camel’s back.
USB-C is very obscure outside of mobile phones (even there most still have the micro USB connector, only the very latest and most expensive ones have USB-C) and Apple laptop ecosystem. It is much more expensive and complicated to implement and few computers have the USB-C ports, so most manufacturers still keep producing USB-A hardware. That your power bank has USB C is logical - it is meant to charge the new smartphones and charging a phone is the raison d’être for a power bank. But find me e.g. a keyboard, mouse or a cheap USB stick with USB-C - and those only the most common peripherals. USB-A ones I can find in every supermarket.
The example with the VGA connector was just that - an example. We can argue technical merits - there I would certainly agree with you (re quality over long cables - well, at least VGA works, but HDMI/DP wouldn’t at all, so the quality argument is pointless there) - but most users don’t care. They care that the projector system they need to connect to has the stupid DB15 plug and the university isn’t going to redo their lecture halls for another 5 years, so that means lugging a dongle around for the lifetime of their laptop. I don’t buy the size argument - yes, the connector is large, but we aren’t talking a smartphone where every millimetre counts. E.g. my Lenovo E31 still has a VGA plug and that is a laptop very comparable in size with the MB Pros. Clients were demanding it, so the manufacturer has kept it in. You can even buy laptops with the DB25 printer port if you really want. The manufacturers are not stupid, especially not in so commoditized market where the customer can simply look elsewhere.
The decision to remove it from Apple laptops was purely a design issue, not a technical one. The same as removing the headphone jack from the iPhone or including only USB-C connectors on Macs. It is being presented as some sort of pushing technical advance but that’s just BS. Since when is incoveniencing your clients by requiring dongles or forcing them to replace perfectly good hw with overpriced “Apple specials” (because nobody else needs these) a technical progress?
