The people I hear bitching the most about PS5 availability aren't even trying, or are not paying customers. Mostly a bunch of people that just want to complain. It's someone else's fault for their problems. Like most other things in life, you get what you put into it. It's the "some people have lives you know," and the "thing should be on the shelf when I want to buy it," types.
These systems aren't even 1/5 as difficult to score as an RTX 3080 anyways. Obviously a bunch of folks have never contended for a highly contested internet drop in their lives.
