There's a long list of incredibly damaging fuckups by software companies, but I can't think of a single example of an existence-ending judgement from litigation.
The biggest reason why billion-dollar software companies continue to release shitty and dangerous products is because they face zero legal liability for their negligence.
If Crowdstrike is litigated into non-existence, it will not be in America, because the law doesn't work like that. Worth noting that there are a lot of software companies in America. This is not a coincidence.
Almost every large tech company in existence has had some sort of fuck up and survived. (Intel CPU vulnerabilities, iCloud security scandal, Sony multiple data leaks, ..).
CISOs buy EDR. In order to kill CrowdStrike, you'd need competitors with similar capabilities who haven't caused similar but smaller and less publicized outages or performance hits (off the top of my head, Tanium and Carbon Black have. I was there.) And that haven't been publicly hacked due to equally boneheaded issues in other products recently (like Palo Alto). So Microsoft... maybe.
Just one example - Fujitsu, associated with the biggest ever misscarriage of justice in England because of bugs in their Horizon software, still going strong...

No class action lawsuit, just some relatives of dead patients settling out of court.
Two years later it had 1 billion revenue.
