The US defense budget is about $1T dollars. They can't spend it all on surveillance, but let's say tech companies + gov spends about this amount per year on surveillance in total. If we can raise the cost to surveil the average person to over $10K/yr, they just lose. This is very doable.
Every little precaution you take will raise the cost, probably more than you think. Every open-source project that aims to anonymize and decentralize is an arrow in their knee. They're hoping that you'll get cynical and stop trying because they don't stand a chance otherwise.
