The Register, a venerable, trusted, Internet news outlet, does not offer any evidence that "cyber security" is behind the data feed cutoff. Since the data feed has been in place for years, and the presence of the feed was extended when some pushback happened, I believe we can conclude that "cyber security" concerns were not behind cutting off the feed. If such concerns truly existed, the data feed would stop and stay stopped until the concerns were addressed. More lies from the current administration.
