Any platform that extracts money from X has the incentive to get rid of any negative reviews about X. Reviewers are not the revenue source. That's why AirBnB, Yelp, Glassdoor, etc will get rid of bad reviews for the right price. Read all bad stuff about AirBnB on reddit, you see where airbnb is heading. People should stop using that platform, whenever you find an alternative.
The incentives are different at different levels of the business. There could be someone with a shorter-term outlook making these decisions, or (more likely imo) it was a very quick misapplication of the policy based on skimming the review. Acting as a first reviewer actually seems like a great application of LLMs, where attention won't flag + they can hopefully be tuned to only focus on the policy-relevant pieces.
