Important Addition:
The Twit OP is missing a few pieces to this claim, which makes it come off as fearmongering (Not going after OP and saying this was their intent. They could likely just be uninformed and that's okay!) Also thank you to the person in the comments finding sources so I can do more research!
Flock will not access your personal data without your consent. It is ultimately the customer's choice to share their data with ICE and law enforcement. ICE cannot tap into Flock and use it as a way to track people down.
However
Flock, unlike Ring, is widely used by businesses, traffic surveillance, security, and much more. Essentially, it is standardized. The go to. This means that a local business owner, corrupt law enforcer, etc can, with their own consent, give their personal data to ICE or other corrupt groups.
Your personal Flock or Ring camera will not be tapped into (You are safe to continue using it to catch porch pirates, lol) unless you consent to it happening. Given how wildly used they are in public spaces, it is wise to stay informed of your town leader(s), local law enforcement's, business owners, etc opinions on immigrants. If you know they are negative views, avoid those businesses, public spaces, and stay aware of what roads, traffic lights, and intersections use Flock so you can avoid that area or inform your immigrant friends to avoid it.
Flock is not the root problem, please don't attack them. It is the people that use their products with ill intent. It runs much deeper.

Please do research and don't believe everything you see! A lot of people are uninformed, and that is okay. Instead of going after them for their lack of knowledge, why not educate them? Thats what I am trying to do here.
