Those 3rd party packages are not a concern for the Thinkpad lines, since the higher business price point supports the lines without the need for subsidizing.
Mac build quality really isn't all that great. Lots of glue and plastic hinges. Motherboard design is also atrocious. Check out Louis rossman on YouTube. I remember seeing a video where the webcam died because a thermal sensor stopped working and for some reason the webcam was wired into the same bus.
They also solder in ram and ssds now. They removed the data recovery port so if your ssd kicks the bucket there's no way to recover anything. That's what the T2 chip is for- they market it as some magical coprocessor but it's just an ARM chip that acts as a drive and ram controller so they can use soldered parts on the cheap.
The keyboard is wonderful and everything except the fingerprint scanner works great.
But maybe people change, and maybe I'm just being paranoid and depriving myself unnecessarily from hardware that I would like. (FWIW, I have used Thinkpads and greatly liked their keyboards, enough that I do consider them for every hardware refresh).
