I think of it as more of a "childhood memories" type thing rather than a bias thing - just like for a child everything they see is novel and new and interesting to them because they've not encountered it before. The internet was the same for a lot of us in the early days because it was novel and new and interesting because we'd never seen or used anything like it before.

Now people take it for granted and we're totally 100% used to it (and it has been commercialised sure), so it is not novel or new or exciting for many of us any more, and we wistfully look back on "the good old days" like we might do the same when we spent hours playing with lego or on an old 8-bit micro etc as a kid.
