In regards to scraping users from the platform your moving away from, Facebook did the exact same thing to twitter in 2013. The veterans running these companies know the playbooks. https://twitter.com/TechEmails/status/1650894515702763521

Its naive that people sit on the sidelines opining they should've done the opposite when all the evidence points to blocking scraping as a standard business practice (and scraping is illegal if the company forbids it in their policy). Most people saying otherwise have not run a company or startup in a competitive environment where every other player wants to steal their lunch.
