I agree with the other comments here saying that it smells of AI-generated marketing puff-piece --- ThinkPads have always been very repairable, with the official service manuals published (which is more of a guide to disassembly/reassembly, but that's sufficient especially given the availability of (leaked) schematics). Older Dell Latitudes are not too bad either.
ThinkPads have definitely not always been very repairable. The t480 was the last solid option, and it went downhill from there.
