One effect that might also be at play here is, assuming that excellence follows a Pareto distribution:

If your team is very good, i.e. on one end of the distribution, most products will be made by teams that are average, i.e. not that good. In that case it is easy to notice flaws.

If you are smart and knowledgeable enough so that you could design/create/implement the products you use easily, you will see room for improvements.
