Yes it does cost more for a company to actually focus on privacy and security instead of lying about it, which is why it is lied about instead of actually being secure
I'm not in favor of Microsoft, I don't say they're the best company that fits users' needs most appropriately; it's well known that they're fined frequently. What I'm saying is this: if people cared about stuff such as privacy, big companies would be more careful with it. Less demand for privacy preservation and high demand for personal information from multi-nationals pushes companies to take advantage of users' privacy.
A business is a reflection of the consumer.
