I'm starting to get annoyed by "experts" who are clearly not familiar with Twitter's stack. Not only that, but she's not familiar with public facts, such as that Twitter became login-only a day before the rate limiting (hence we can seek cause-effect relationship in Twitter's own actions here, as one hypothesis).

This kind of random guessing from people in the field, without the specific facts on the table is much like what I can ask GPT to generate. Plausible, but completely wrong.

In this case I suppose what prompted the entire blog post is the self-advertisement in the end, as this developer offers a commercial rate-limiting product.
