Ifixit focuses on some weird criteria. Like pentalobe screws are annoying but not a real impediment to repair. Soldered NAND is a wear item and a WAY bigger deal.
Repairability is a process not a factual end state, there are tradeoffs in design.
I do a lot of repair work (ex EE / production engineer) and I’ve been shot by poor parts and tools from them. I look elsewhere first.
As for ifixit I would treat the products sold in partnership with the OEM differently from the ifixit brand ones.
Honestly I'd rather go direct to vendor for parts or service and decent turnaround and there's only one that offers this I can name.
The problem is we have too many captured markets. I have a furnace yet as a user I'm not even allowed to see the manual. The HVAC people lobbied the EPA to make it hard for anyone but them to work on furnaces.
"Citation needed". For anything resembling normal usage an SSD will last well beyond the economic lifetime of the rest of the components surrounding it. So why is it that big a deal to replace it?
Literally 99% of laptops out there die and/or are recycled with the stock configuration.
The first thing to go are the ports, batteries, screens, keyboards. I haven't seen an SSD failure in a decade now and we have thousands of them in production and on people's laptops.
