Most issues that you reported have been user errors, firmware issues or simply to vague to reproduce. We do quite some testing (despite you not believing this).
Nowhere did I, or anyone from ultimaker claim that this was a reason. Why do you keep repeating this point? I actually agreed with you in a previous post.
Failed patch? Can you explain how / why 3.5.1 is a failed patch? Because we consciously decided to leave certain bugs in there to ensure that there was stability (which you are arguing for that we should strive for). If that's the case, I'm confused.
Fair enough. If I recall correctly it used to do this.
Bricked? Cura isn't deploying any firmware update. So how would the Cura 3.5 brick your machine in any way? I'm getting the feeling that there have been issues with the operation of your machine that you've not shared here, but are blaming on Cura 3.5. But again, as a software engineer with 35 years of experience, you would know we need logs to diagnose your problems 😉 Based on the fact that you are the only one with these kinds of problems, it does have something to do with your system / your actions (which still means we need to fix them, but it also means that we could not have found them with the testing we did).
Most of your comments regarding bashing (or the perception thereof) are, I think, because of the way that you explain things. You seem to assume that because mistakes were made that the other party knows nothing about software, development or testing and subsequently explain the entire process as if you were explaining it to a first-year student. Although you might not mean it as such, it feels smug and derogatory.
I think it's a far shot from going "Hey, there are some bugs in there" or "Hey, I'm seeing a weird bug that I feel should be obviously checked in testing" to "Nothing has been tested and you don't know what you are doing". This on its own is probably also why it's seen as bashing since others are not experiencing these issues (and thus claiming that its a "disaster" is a bit of an over exaggeration)
See my previous paragraphs. Although valid advice, it gives the impression that you believe that we don't know this. We do. We also follow the advice.
