In just about every other industry, consumers have many ways to get faulty products replaced. Many companies offer meaningful guarantees and warranties. Consumers may successfully sue manufacturers for damages from defective products, especially if the manufacturer was negligent. Manufacturers have been forced to disclose information about the quality and dangers of their products. The old buyer-beware attitude is out.
Consumers now demand that sellers be accountable for how their products are used.
Consider a typical software installation process. Typically, you will find you have given consent to absolve the vendor from any responsibility whatsoever. Yes, you will have absolved the vendor of responsibility for known defects in security that would lead to a compromise of your confidential data. Yes, you will have agreed not to blame the vendor for a rare combination of commands that will wipe clear your entire disk. Even the few, ephemeral commitments contained in these warranties are worthless.
