All of the complaints you had are extremely reasonable reasons to not want the Framework 16 (or any Framework). While I personally am quite happy with mine, I very much believe that it is not for everyone, and in fact has quite a niche audience. That being said, most of your complaints should have been obvious from viewing images or reading any of the numerous reviews. So yes, I agree with the GP comment that you seem to have bought the computer without knowing what you wanted and/or what the Framework offered/was.

Being more expensive, heavier, and worse "fit and finish" is pretty much the tradeoff for upgradeability and repairability. Not everyone values those things to the same degree, and deciding that those tradeoffs are not worth it is completely reasonable. I just don't understand how you could get wind up buying one without knowing those were the tradeoffs you were making. I've read almost every one of these complaints in previous reviews. It's not exactly a secret.
