Are comments like these bought and paid for?
USB-A: It's environmentally responsible to offer backward compatibility, at least for the life of existing products which for external hard drives, printers, scanners, mice, is actually a very long time sometimes. Five years would suffice. I still cannot buy a cheap USB-C external hard drive, but had to buy an SSD for 5x the price per GB.
Really? What's cheap? $60 https://www.amazon.com/dp/B0792DP87N/ref=twister_B07CVVP5X8?_encoding=UTF8&th=1 - sounds like you just wanted an SSD and looking for a reason to justify your purchase.
MagSafe: This has prolonged the life of my MBP by years. Other laptops are frequently on the ground when someone's foot yanks the cable. Also environmentally responsible because I have now bought about 4-5 USB-C cable replacements in one year for charging - the small size of the connectors means they are flimsy and the cables are pretty fragile, whereas my old MBP is still on its first charger and cable.
Why is your computer on the ground? If you've bought 4-5 USB-C cables in one year for charging, you're doing something wrong and not taking care of your cables. There's nothing flimsy or fragile about them. I just had to retire my first lightning charging cable that came with the first iPhone that had lightning. Only because the sheathing started to "rot" away in one part. Cable/braid underneath is just fine.
Touch Bar: Good luck to you. I don't like it or use it except when I need a function key or need to change volume or brightness, which was much easier without it.
You could have gotten the non touch bar model?
SD Slot: why not wireless? Because once you buy a high end camera, say you spent $10k or more on it, you are not going to want to upgrade it just because Apple said you should. It's just rude of them to remove the SD slot.
Tech changes. Either adapt or pick something else. You can get an SD card reader (usb-c to sd) pretty cheap. I can tell you those SD card slots were pretty freaking flaky to begin with.
This is not progress, but devolution. It's only because of the narcissistic PR department of Apple that they are blind to the fact.
It's progress. It's just you don't like it and don't like change.
