The Vice article refers to it and the CEO's tweet:

> In 2019, former Kraken employees posted scathing comments about the company on Glassdoor, a website where workers write anonymous reviews of their employers.
> “Kraken is the perfect allegory for any utopian government ideal,” one reviewer wrote. “Great ideas in theory but in practice they end up very controlling, negative and mistrustful.”
> In response, Kraken’s parent company sued the anonymous reviewers and tried to force Glassdoor to reveal their identities. A court ordered Glassdoor to turn over some names.
Kraken's CEO's notion of "free speech" appears to extend to exactly the periphery of criticism.
