I wish I could argue specific metrics for why Mastodon is better than Facebook, but the proprietariness of Facebook prevents us from even doing that. Case in point? If I want to determine post reach in Mastodon I can just look at the code and crunch some numbers because I know how the algorithm works. With Facebook I would have to create hundreds of test accounts and stage a test environment. It's a science like exploring the unexplored universe despite being a human creation. That's wrong.
