As far as what we can do about it...it's a "trying to get the toothpaste back in the tube" scenario now. Any type of surveillance shouldn't be there in the first place. But, as long as the population continues to use apps and agree to location enabling, it may be beyond fixing. Making rules after the fact will exclude some person or entity, and with so much collusion between lawmakers and corporations I think privacy will now always be exploited. Stop using smartphones is all I've got at the moment.

On a tangent, I strongly feel "we the people" need to watch what congress is doing more closely. Proposed laws and resolutions are posted, and while some are lengthy maybe it's worth the time to read and interpret them for ourselves instead of relying on media to do it for us. Forming a group to do this may work, as no one has the time to read everything.
