"Should there be a statute of limitations on the digital information the government can keep and store on you, if any at all?"
You answered your own question: They have NO right to keep/retain information at all. If one is suspected, a search warrant then must be issued, while still retaining 5th and other Amendment rights. It is THEY who have the burden.
This thing wreaks of thought crime and elimination of natural-born/God-given rights in a totalitarian society, where corporate/private elitists decide who will serve and who will pay to fund their profits.
