It really completely depends on the ATM. Some ATMs require identification(mostly depending on how much you're buying as far as I know), some have cameras on them, and some, both. If a certain bitcoin ATM doesn't have both, then the price premium might(?) be worth it depending on how strict you are in terms of personal privacy. Buying(or selling) BTC on Bitcoin ATMs can get really really costly though; and I'm personally really not a fan of paying price premiums.
And all in all, aren't such things contrary to the idea of cryptocurrency on the whole if you have as much anonymity when working with it as you do with fiat?
I mean, it's different from person to person. Some people are fine with buying/selling through KYC exchanges like Coinbase, and some prefer doing it through more anonymous platforms like Bisq. It just depends on you honestly.
