This. And one of those four ports is needed for power supply anyway, another for a display. Magsafe covers the first (and drastically reduces wear & tear from the rather flimsy USB-C ports) and HDMI can cover the second, but you don't have to use it, as there still three USB-C ports left just like before.Most people never use all four of their USB-C ports at once. And when they do, they are using one of those for power, anyway, which won’t be necessary on the new machines. This change is fine.
A few people asking for six identical ports, for what? Sounds like hardcore desktop use. Then get a desktop or, wait, a hub. You told us the same in the last 5 years.
People who actually use the Macbook as portables are happy to have a standard port for projectors, displays and TVs integrated. The same goes for SD card. That silly argument 'I don't know anyone using it, not professional' is nonsense. The majority of consumer and prosumer cameras have SD, same for most TVs, receivers, car radios, audio and DJ equipment, including most recent high-tier releases (Pioneer, Denon). UHS-II/III is really fast, too. And again, if you don't need it, either ignore it or stick in a Nifty Mini Drive to expand your internal storage for cheap money for the files you need less often (TimeMachine backups both). Also you still have your USB-C ports. No reasons to complain.
3x USB-C + HDMI + SD + Magsafe > 4x USB-C
Fully agree with the OP. A few will be less happy, that's okay, you can't cater to everyone. But the majority of users and reviewers who had been frustrated since 2016 will enjoy this as valuable upgrade.
