Seems like the solution de jure to problems for both government and business these days is to dump the problem onto the citizens. How about some excellant analysis and creating regulations and laws with money for enforcement to solve these kinds of problems instead? Heck, the regulations and laws are probably already on the books, just use them. Misinformation is not magic, lies should have consequences in some arenas. Speech should remain free in general, including ChatGPT bullshit, but not everywhere. Communications fraud is a crime:

Social networks are a telecommunications service so profit (including gaining political power) from misinformation should be prosecuted as fraud. If the courts can not figure out what misinformation is, everything is doomed anyway.
