The main goal of their foundation is to support education, not to satisfy a "pro" market.
Just because people use them as tools doesn't mean they change the charter of their non-profit foundation

I'd say the other way around: the "pro" people should go find another board to use, of which there are many.
I interviewed in person at a leading industrial automation company over five years ago. They were looking for someone to work on ARM stuff and I was (naively) proud of the work I'd done with the original Raspberry Pi in school. The hiring manager had never even heard of the Pi...
Industrial IoT does use Pi's a fair bit, but this is IMO a misuse (I'm guilty of it too) and in the long term can be a disservice. The Pi is a great platform for a go-to-market product, but they have many shortcomings that for most use-cases in industry are showstoppers (most notably, Pi's will often fail without warning, or their "disk" will become corrupt). More expensive industrial products are out there and typically are more robust, and designed in a way that they can be more seamlessly integrated to a product - once the upfront costs are paid (both in development and dollars).
What really needs to happen is other manufacturers making the development on their hardware more straightforwards. What the Pi foundation has done is shown that companies and developers want to just be able to run a widely available and minimal linux distribution and not have to muck about with proprietary and poorly documented SDK's behind closed doors.
You get what you pay for. But this is beating a tired horse that I'm skeptical was ever true to begin with. Are the people with SD card corruption just using crap cards to begin with? I've used a pi4 and rock64 and neither had any disk corruption. Plus you can boot on USB today. And fail without warning? Is that really a thing? No sensor saying there is a heat problem?
You can definitely reach for an industrial product with similar specs. But just keep in mind that niche products may have even less market testing than a Pi. There is some truly crap hardware and software out there that people suffer with simply because it's the only player in the niche.
The SD card is probably crap like you say but it can be formatted and passed read/write verification testing when connected to a PC which is a bit weird.
It's much easier for Raspi foundation to release a more industrialized version than it is for another manufacturer to create this support and community. They could still operate on their non-profit mission with the profit.
Industrial microcontroller and embedded companies do need to also make their software and docs better. There seems to be some modernization but it's slow.
Ssssh. That's blasphemy here.
Any other ARM platform mentioned here gets downvoted and shouted down with "But it's not $40!". Let them play with their toys and leave them alone.
