1> The Github Repo would probably be the best? Granted you need to understand how the workflow works first before you can even understand it. If you just want general news then most media would work, just cross reference them to make sure they're accurate
2> Research. Usually finding the root of the news would be more than enough.
3> You already answered it, "depends" on the country. Some countries have limited access to crypto itself iirc, some to Bitcoin. Some don't have any!
