You risk making discourse difficult when you continue punishing people who are attempting to do the right after doing wrong for a while.
This example will be ammunition in internal debates about how much to weigh product pressure vs engineering suggestions that improvement is technically possible; the next time an eng says "let's look at this slowness one more time, it may be fixable more easily than you think", they might be listened to.
lol without context you'd think something tragic actually happened here.
I can't believe you're missing this huge point.
On the other hand, a few days of doing the absolute bare minimum of quality control doesn't undo a decade of actively hostile practices. They're still very very deeply in the red when it comes to their relations with the playerbase and for good reason.
Paying $10k to the person who documented this bug is a good start, but you need to do a whole lot of work to make up for the impressions caused by that kind of prolonged systemic negligence.
Have you heard the one about the country with the death penalty for all crime? It just leads criminals to maximally try not to get caught, without regard to damage done [i.e. removing all witnesses to even the smallest crimes]. This isn't what you want; even within "negative" relationships both sides lose when you don't have a gradient of responses.
A criminal prosecuted for murder and petty theft simultaneously can't really go around complaining that they got 25 years in gaol for stealing an apple, but if everyone had already known about the murder and dealt with that accordingly it'd be pretty harsh.
(not that fixing a bug is exactly a criminal act, but the general principle remains)
