For a beginner, I’d probably stick to Github initially, just because there’s so many guides and tutorials on how to use it, and their free plan is still pretty generous.
A lot of the knowledge is transferable though. If you do want to try something else, Codeberg is pretty good for open-source.
To just learn about Git, you don’t even need a host like Github or Codeberg. You can have a Git repo just on your computer, and still get a bunch of the benefits of source control - a full history of everything, separate branches and worktrees so you can have multiple incomplete changes and switch between them, etc.





Companies sometimes sell their own first-party data, but not nearly as often as people think. If a company has data that other companies don’t have, a lot of the time they’ll want to keep it for themselves, since it can give them a competitive advantage over other platforms.
If Amazon knows what movies and TV shows you like, they’re going to use that data to improve ad performance on their own platforms - suggested content on Prime Video, product ads on Amazon, etc. They’re not going to give it to some other company to use.
The one major exception to that are data brokers. These are companies that only exist to sell data. These are less well known companies. They often use public data and combine it with things like supermarket loyalty data and purchase history.
