x86 has bit manipulation instructions for any bit. If you have a book stored in bit 5 it doesn’t need to do anything masking, it can just directly check the state of bit 5. If you do masking in a low-level programming language to access individual bits then the compiler optimization will almost always change them to the corresponding bit manipulation instructions.
So there’s not even a performance impact if you’re cycle limited. If you have to operate on a large number of bools then packing 8 of them in bytes can sometimes actually improve performance, as then you can more efficiently use the cache. Though unless you’re working with thousands of bools in a fast running loop you’re likely not going to really notice the difference.
But most bool implementations still end up wasting 7 out of 8 bits (or sometimes even 15 out of 16 or 31 out of 32 to align to the word size of the device) simply because that generally produces the most readable code. Programming languages are not only designed for computers, but also for humans to work on and maintain, and waisting bits in a bool happens to be more optimal for keeping code readable and maintainable.
I think with how current economics work it could also be useful to fine all shareholders when a company commits a crime. Ideally fines in percentage of the current stock value, and perhaps even in two parts, half applied immediately to affect all current shareholders, and the other half applied a week or so later to maximise panic-selling and make the stocks undesirable to force stock prices to make a nosedive.
It’s often mostly shareholders that actively push for enshittification, and they often don’t feel any of the financial consequences of fines on companies as long as the line still goes up. So if you fine in a way that shareholders are negatively affected and stock prices (which is what holds most of the wealth of many shareholders) to plummet then I think that’d be much more effective.
Though jailing CEOs for crimes of their company would still be effective for private companies (though they seem to participate a lot less in enshittification as they focus on long-term strategies instead of maximising quarterly growth above all else). For public companies a CEO is often mostly just a scapegoat for the decisions made by the board of directors and shareholders.
