For a long time my assumption has been that well funded government agencies can, and do, slurp everything I type. (Even though that breaks several laws.)
That has little to no effect on me. But private companies do - they lose the data; they're open to blackmail or corruption; they're insecure; they inaccurate; etc.
Many more people are caused harm by Equifax listing someone else's debt problems under their name than by the NSA doing whatever it is they do.
This post is not saying that government surveillance is acceptable, or that we shouldn't do stuff to stop it!
How do those issues not apply to NSA / GCHQ?
It is really difficult to sue a company that has a team of lawyers while you are a individual just trying to get by, esp. if said private company did something that really disrupts your life, like wrongly foreclosing on your home or wrongly firing you.
2) Some people manage to obtain justice when they are wronged. Often it's just not that easy.
This is not at all true, unless you're referring to penalties (civil and criminal) imposed by the government, with the underlying threat of force.
