Congratulations on writing the most servile corporate apologia I've seen all week. This is a masterpiece of Stockholm syndrome.
"Accountability means money and paperwork." Beautiful. Just beautiful. You know what else means money and paperwork? A protection racket. "Nice app you got there, shame if something happened to it before it reached customers. That'll be 30% please." But sure, let's call extortion "accountability" because Tim Apple said so.
Your driver signing example is chef's kiss levels of missing the point. Microsoft said "hey, sign your drivers so we know they're not malware" they didn't say "only drivers we approve can run, and also we get a cut." You're comparing a bouncer checking IDs to a mafia don enforcing territory. These are not the same thing.
And oh my god, the Nintendo argument. You're seriously holding up Nintendo's lockout chip as consumer protection? The same lockout chip they used to squeeze third-party developers, control game production, and maintain an iron grip on pricing? "Until Nintendo cleaned out the garbage" yeah, they cleaned it out alright, straight into their own pockets. The video game crash was caused by publishers like Atari flooding the market with garbage like E.T., not by independent developers needing more "accountability."
"The future is signed code with deep identity verification for every instruction." Holy hell. You're not describing a security feature, you're describing a prison. You're literally fantasising about a world where every line of code needs corporate permission to execute. That's techno feudalism with RGB lighting.
This isn't about protecting anyone from bugs. It's about trillion-dollar companies convincing people like you that you need their permission to use the computer you bought. And somehow, SOMEHOW, you've decided this is good actually, and the 1980s with its freedom and innovation was the problem.
The fact that you think general-purpose computing is a "danger" that needs to be locked down says everything about how effectively these corporations have trained you to beg for your own chains.
