The “underhanded tactic” they were referring to was not acknowledging bugs so sales might go without impact.
I don’t think anyone here has said or implied blizzard breaks or implements broken things for fun.
And yes, after observing your posts for a long while now, you do always come off sounding smugly superior as you tell people they must complain in a manner you’d normally see from a paid tester or offer near-useless advice along the lines of “reload ui”.
I would suggest not inadvertently riling people up who are already upset. If they’re complaining the wrong way, just let them. If it’s useless to blizzard I’m sure they can handle that. It’s not everyone’s job to write proper bug reports in full detail. Sometimes a simple “this is broken” without explanation but posted by a thousand people would, I’m sure, get them to think “maybe it’s worth investigating or asking about”.
