It always makes me laugh how, for years, we mocked journalists because of their inflated blue check egos, and now every "free thinker" out there is eager to pay to be just like them. Verification is meaningless for most individuals since there's no real need to verify if @ronny2938742 is indeed Mr. Ron Whatever.
However, it's crucial to know if an account claiming to be a big company, government agency, journalist, politician, etc. is legitimate. Opening verification to subscribers is absolutely scammy, just a way to make a couple of bucks off the victims of culture war brainwashing.
