HDMI to micro-HDMI is just a straight passive adapter - only the physical shape of the port is different, and feature support isn’t really a thing. In this case it’s obviously done because the HDMI connector is annoyingly bulky if you want two of them, though I’m surprised a stacked connector wasn’t a better option.
Stacking is risky, because the end of cables might be unreasonably large, thus two might not fit on top of each other that close. Also HDMI cables tend to be pretty bulky, they might simply strain the board too much?
Sure I can just buy an adapter, but then I have to keep track of the adapter and always deal with an adapter hacking of the board making it more awkward to handle.
You make it sound like they are being unreasonable, but just like USB-Micro to USB-C and X to headphone jack, it's a huge inconvenience when you can't find/don't have it to hand.
I used to lose the Micro to C adapters all the time, I lost the C to headphone for my OnePlus6T while travelling and was unable to find a replacement so no headphone use for me.
Also, I have about 12 Raspberry Pis, as many display devices, a dozen or so other HDMI devices such as consoles etc, and tens of normal sized HDMI cables lying around and they're all compatible.
You're not wrong, but it feels like an unnecessary problem to have, stacking a couple of full size HDMI ports would have been nice, or just putting a single port on since having two on a Pi is kinda unnecessary.
If I remember correctly (and that's a big if), DisplayPort started royalty-free but then they introduced royalties. From my blurry memory: I checked once many years ago and it was free, but then I checked again a couple of years later and it wasn't exactly free any more. Did it change again? Or am I completely wrong from the start? If someone remembers the history better than I do...
More common in monitors perhaps, but I don't think I've ever seen a TV with a DP input. Since AFAIK the target market of the RPi is "plug it into a TV, plug a cheap USB keyboard and USB mouse, and you have a working computer", having HDMI output is a requirement.
Exactly, you can solve the dual-display problem via daisy-chaining a couple of DisplayPort monitors instead. Using Micro HDMI was a bad decision in my opinion.
