My initial comment also mentioned why developers hated the SD card slot. To quote Koush

The SD card needs to go away. It's a nightmare for developers. There's too much variability here. SD Cards can be slow, resulting in poor app performance. They can come and go, or be swapped, and that results in unpredictable behavior if an app was expecting an SD card. One contiguous block of data needs to become the standard here (with different OEM SKUs for more/less storage), as it has been on iOS since the first iPhone.

The comments from Linus came from an industry insider he said he trusts. I would be inclined to believe him since he used to carry a Note9 and was a massive advocate of SD cards.

Also don't think the reliability of the cards was an issue when I got them, they were high rated Samsung and Sandisk models.

And 128 GB is almost nothing, kinda proving my point that this is more of a use case point than an argument against the feature.

You're looking at this from the point of a power user and not the average person. Most normal people just get the base variant when they see it has 128 GB and are happy with it.

They're objectively more reliable than cloud storage though, should you ever go somewhere where network connectivity is an issue

I mentioned I dislike cloud storage but with USB-C ports I can actually use my external SSD or a USB drive to backup my phone if I want to although it's not something I do often.

Given that they're still using Bluetooth, which is still terrible with any interference, low bandwidth, and has the same tedious connectivity problems it's had for the past decade...I'd argue we have yet to see that progress where it matters.

When was the last time you used a Bluetooth headset? I had issues initially in 2018 and 2019 but things like the Galaxy Buds+ and newer generations of truly wireless earbuds have fixed the connectivity and interference issues. Some Bluetooth headphones support LDAC and LHDC codecs which allow for high bandwidth. LDAC is part of AOSP so it should be on every Android phone running Oreo or newer unless the OEM has removed it for some reason.

If that were true, there wouldn't be so many people vocally expressing why new products aren't adequate without these basic features.

That's because there are a small group of enthusiasts who are extremely vocal. Most people have moved on, they may want one or both features but they aren't dealbreakers for them. Also wouldn't say a bunch of enthusiasts complaining means it expresses the sentiments of everyone. Look at the outcry about the iPhone mini, it didn't sell very well but online communities would have you believe it was the most popular device of that lineup.
