I mean, I definitely get the paranoia, but people have wiresharked it left and right, and every day... it doesn't. They do harvest what you do on the metaverse, but that is basically gone now anyway, and was always optional. They collect data from any first party products, but like the headset itself, no. It doesn't send anything. And that isn't something you can hide. Like the signal literally has to be sent, and it would be detectable.

They definitely have over the years kept mentioning things they would like to do, like using eye tracking to confirm to advertisers that ads were actually watched and shit, but that never actually came about. The only eye tracking they made so far was on the headset they didn't target at consumers. I'm sure they still have future plans to achieve some of their horrible goals, but as of yet, hasn't happened.
