Yeah, and that's kinda sad. However, old Thinkpads are still totally usable. I was using T420 until a year ago and the only thing that I hate about it was the absolutely awful screen. It was 1600×900 with absolutely horrible colors. There's a few ways to install a better display but it might be tricky [1].
Otherwise it was a decent “daily driver” laptop, in many aspects superior even to current gen MacBooks, particularly repairability, ports, keyboard quality. I'm using a 2020 MacBook Air now which I bought to try out the M1, and some aspects where it excels are screen (obviously!) and speakers, but I think those are comparable to a little more modern ThinkPads (xx40 maybe?).
