You can buy some parts for the steamdeck but not the mainboard despite them claiming you could buy every part when they announced the partnership. iFixit has been getting just a littttttle bit sus honestly

I think it's worth being clear about the scope of the rating. iFixit has always been about repairability defined by parts availability, and its ratings consider software restrictions only to the point where it interferes with the user experience when replacing parts to restore things to the original performance.

Customizability (in software or otherwise) isn't part of the score. Durability/longevity isn't part of the score, either. Those are things that I want, too, but I can recognize those are outside the scope of what iFixit advocates for.

I do have some concerns about the partnerships creating a conflict of interest, but sometimes that feedback loop is helpful for improving the product, where the maintainer of a standard also has a consulting business in helping others meet that standard. Ideally there's a wall between the two sides (advisors versus raters), but the mere fact that one company might do both things isn't that big of a deal in itself.
