Their job is to sell tools to fix stuff, did you even read the ars article, it's just clickbait. Lenovo failed because they didn't provide repairability score for their laptop models. nothing to do with if it's actual repairable or not.

I've repaired Lenovo before, aftermarket items all available, change screens, keyboard, battery, simple stuff only though, no issues, everything is designed so it's easy to change.

I would not say the same about HP or DELL, shit enterprise laptops, and the consumer ones are worse.
