This says it. Actual "tech" circles were historically not super into the Mac. Of course there were some people who loved it, but the bulk of the classic Mac fanbase was design type people and people who were mostly recreational PC users but had way more money to spend than typical PC users. More hardcore tech folks were turned off by inflexibility and OS instability by the mid-90s.

This has of course changed over the past 20 years as all the OS limitations with the Mac were lifted and all PCs have kind of matured and you don't have massive increases in speed every year. So Apple's better quality, closer price parity, and better software support started to look better and better to actual tech people.
