I do find it humorous that “too much performance” is seen as a negative, though.With few other things to complain about, though, I guess that’s where we are!
You are taking what I am saying and twisting it. More performance is great! My issue is that the iMac was intended to be a computer for normal people who are not churning through terabytes of video files. The 27" was for those who mostly had some money to burn and wanted a larger screen with the potential of something with a little more power. Currently, they are telling those people they either downsize to the 24" or pay for something they do not need or even want. They have created a hole in the lineup and are forcing people to downsize, upsize, or leave macOS. That sucks and I don't think highlighting it is complaining. I see it as far more reasonable than defending a company who is gouging you, but different strokes!
Also, I disagree with your statement on power. It has been within the last 10 years that we have started to see machines that are far more powerful than people need. This really mostly coincided with the adoption of SSDs, but also with power consumption-conscious chips. 2015 or so seems the cutoff in my mind, though you could argue as far back as maybe 2012/13. If you have a computer from that era, it probably feels relatively snappy for most tasks.
