A lot of the WiFi and BT issues were due to proprietary firmware blobs which weren't included in package management repos either due to licensing issues or decision not to pollute OSS repos with nonfree software.

This has mostly been solved by either putting them in the nonfree repos or just the fact that WiFi hardware vendors aren't using such stuff anymore.

I still remember pulling firmware blobs for my Broadcom cards, then it magically worked fine. It was far from trivial and I think that's what caused a lot of people who tried Linux on laptops in early 2000s to turn away.
