Yes, rather than actually lodge a bug report, so that the issue could be properly investigated and fixed, you decided to just spread FUD about the package on public forums instead.
I didn't ready anything FUDdy in his post. Just carefully worded and reasonable warnings:
1) He had some problems after installing BB3 and BB4
2) He did not track down the problems, but rather corrected them by rolling back to BB2
3) Recommends having a backup before installing BB3 and BB4 -- BB1 and BB2 make this recommendation, as well.
No fear, uncertainty, or doubt there, IMNSHO: 1 is a statement of factual experience, 2 is an admission of not wanting to be bothered finding the problem, and 3 is good and solid advice before making any changes to a critical system. When queried further, he just said "things" happened to him that he didn't want to bother with. Another perfectly valid response when something goes wrong and you lack skill, time, or wherewithal to troubleshoot. Nor is anyone obligated to do so, let alone make a report on the grounds that "something" is screwy.
It's happened to me in the past with other software packages, and no package nor collection of packages are immune to something going awry, given the massive variety of system configurations which exist in the wild. Nothing here worth taking offense to.
