Honestly, who cares if it is now run by the FBI? If you're worried about it, use a VPN and don't post any personally identifiable info.

If you're unsure how to use a VPN or where to start, just switch to the Brave browser (which is honestly the best browser available anyway) and pay for their built-in VPN service.

Unless you're specifically targeted, you'll be fine. And if you are specifically targeted, it doesn't matter who owns this site.
