It is possible to build a bridge which doesn't fall down during normal use. Has any company demonstrated that it's possible to build large scale software with no security flaws in it? Microsoft haven't, Apple haven't, Google haven't, Facebook, IBM, Oracle, RedHat, Amazon, Cisco, Juniper, The Pentagon, The Whitehouse, The UK Government, the fact that we've heard of Snowden suggests the NSA haven't, banks haven't, airlines haven't, medical companies haven't, Cloudflare leaked memory to the world, Symantec screwed up SSL authority handling, BGP was hacked to steal cryptocurrencies. It's possible to commit to building a bridge and then everyone must wait patiently for the bridge to be finished - there's no push to have the bridge done in 6 weeks because another bridge is being built in the same place and if it appears soon all the traffic will be lost and the build cancelled.

Who even stands a chance? Colin Percival - math prodigy, cryptographer, former FreeBSD security officer - has paid out thousands in bounties for over two hundred bugs in Tarsnap software (not all security flaws) including buffer overflows, divide by zero, double-frees, mistakes in error handling, Unicode string handling error, numeric overflow mistakes, padding errors, user input handling bugs and one "critical security flaw" (against his very high standards) - https://www.tarsnap.com/bounty-winners.html

If someone like that working full time on a very constrained single purpose product can't make flawless software, what sense does it make for you to sneer at Microsoft as if Windows is singularly flawed here?

> "If Microsoft products are so infallible when used as instructed by Microsoft, then why would Microsoft have a heart attack as Snowden suggests."

They aren't, they're Swiss-cheese. So is approximately every other general purpose computing product, software and hardware, with the possible exception of a handful of very small very specific battle-hardened tools. Even the non-general-purpose walled garden appstore devices are Swiss-cheeses.

Possibly their heart attack would be because they are one of the biggest software development companies on the planet with a huge range of products used in tons of companies, so such a regulation would disproportionately affect them more than most companies? "All" Facebook develop is a web page, and very few companies use Facebook or Instagram or Oculus except by sending money and adverts to Facebook. Microsoft would have to secure a ton of large-scale software used on company premises in environments they have no say in. Seems to me the result of such a ruling would be something like Microsoft stopping selling on-premises software entirely and offering only web access to hosted Outlook, Office365, SharePoint, SQL, Biztools, Dynamics, with a ton of extra checks slowing them down, and companies faced with either using Microsoft online tools where Microsoft is responsible for the security or choosing on-premises tools like LibreOffice and Thunderbird and FireFox where they have to take responsibility, their legal and insurance would push them to Microsoft world with even less configurability or interconnectivity than there is now. It may be more secure, it doesn't sound great.

> "Instead we frequently see discussion blaming users of the software, i.e., Microsoft's customers, or even suggestions to make the customer liable, or comments from "security experts" on how Microsoft has made such amazing strides in securing Windows (a tangent)."

Not a tangent; Look at the recent discussion on HN about Windows Defender, and pretty much any security choice - it's full of people bemoaning Microsoft making decisions that are mildly inconvenient on the grounds of "how dare they think they know better than me", "I demand to be able to turn these security features off", "I want control to be able to do anything". If Adobe Reader is vulnerable and lets someone ransomware all your documents, what benefit is it to you if Windows underneath is an impregnable fortress? If someone can steal a user's 2-factor auth backup code from their house and access their remote VPN and exfiltrate data, what good is a perfect OS underneath doing for anyone?

This isn't whataboutism ("others are insecure so why can't Microsoft be"), and although it is somewhat in defense of Microsoft it's not "waah leave Microsoft alone", it's ... what kind of world are you living in where you heavily imply that Microsoft could have done differently and didn't? Microsoft trying to write Windows 3.1 in Pascal or ADA would have had their lunch eaten by every other company which didn't.

> "What a remarkable state of affairs we have today where employers such as Microsoft can call their employees "engineers", and yet both the employer and employees are absconded from any liability for the so-called engineer's work."

You think changing their job titles to "programmer" would improve the situation?
