How far does that list go? I indeed don't use Sony software and I avoid Microsoft's. I don't know many other violations of this severity. For example, Dell had pre-installed root CAs (but weren't persistent like Lenovo's), and many other laptop manufacturers haven't preinstalled root CAs (e.g. HP hasn't afaik).

With Framework and System76 and other smaller manufacturers making Linux-first laptops, I'm especially disinclined to ever consider Lenovo again.
