I'm guessing yes, it's related to funding (why it's free) and verifying ID. Normally they'd set up a pop-up clinic somewhere and offer them free for anyone that could show up. So they lower the barrier for entry by allowing you take it at home (good) but require a Zoom call (not good) to be in compliance with reimbursement / grant funding agreements.
They're trying, but I am guessing we're going to start seeing lots of stories about how the system (Zoom) is overwhelmed and people are getting disconnected, invalidating their ability to submit a test. Better would be to have some type of Uber partnership where someone shows up to your front door, has you spit in the cup and they drop off a whole bunch at a lab after collecting a few dozen in a specific neighborhood or region.
