Count me not surprised.
A company that goes out of their way to dispute the CVE, to turn around a day after a PR firestorm, is not actually turning around. They are saving face.
The apology was loaded with blame shifting and bragging about previous H1 payments, neither of these lead me to be more lenient with Valve.
The hacker is still banned from submitting bugs, for god's sake. Nor has he heard from Valve.
Edit: They even disputed the CVE, manually, removing any doubt that this wasnt an oopsie caused by a system.
Valve is coasting on prior success. If discord or curse was done better steams market share would nosedive.
This is one of many mistakes that happen when you dont compete and innovate.
