Here's what the bulletin actually says
"Through the remainder of 2021, racially- or ethnically-motivated violent extremists (RMVEs) and anti-government/anti-authority violent extremists will remain a national threat priority for the United States. These extremists may seek to exploit the emergence of COVID-19 variants by viewing the potential re-establishment of public health restrictions across the United States as a rationale to conduct attacks. Pandemic-related stressors have contributed to increased societal strains and tensions, driving several plots by domestic violent extremists, and they may contribute to more violence this year.
Foreign and domestic threat actors, to include foreign intelligence services, international terrorist groups and domestic violent extremists, continue to introduce, amplify, and disseminate narratives online that promote violence, and have called for violence against elected officials, political representatives, government facilities, law enforcement, religious communities or commercial facilities, and perceived ideologically-opposed individuals. There are also continued, non-specific calls for violence on multiple online platforms associated with DVE ideologies or conspiracy theories on perceived election fraud and alleged reinstatement, and responses to anticipated restrictions relating to the increasing COVID cases."

Doesn't sound Orwellian to me at all.
