It seems to me that Lenovo’s repairably is more affected by that iFixit partnership than the opposite. I don’t see anything factually wrong or suspicious in the article.

I use iFixit's guides all the time, so I would hope that their score isn't affected by it. I've seen them as being fairly good at their role.

As someone who has changed a laptop keyboard before.

That picture says it all.

They even state it them selves in the article, so it is not like they are trying to hide this. Also they say that this is not the end all be all of reparability, which IMO should merit not then getting a 10/10 but idk what their metrics are.

This is true, but they're also not wrong that fully-modular USB-C ports is an absolutely huge win. It's one of the biggest things when it comes to laptops these days.

It's unlikely that fact will change the repairability of the devices. They risk too much by posting biased and false information on that end.
