The odds of something actually happening after Elon says it will happen are roughly 10%

To be fair, I didn't read the article...

But how would one open source an algorithm? Wouldn't it be the implementation of an algorithm be what is open sourced?

I hate the overuse and frequent misunderstanding of this word.

Last week, my twitter feed started being filled with random political posts and engagement bait. It got so bad (about 70% is stuff I'm not interested in), that I've finally stopped using twitter.

I guess this could explain why the algorithm changed so suddenly.
