it's the "afaik" that's important. You don't know. You have no way of knowing. I personally won't use a mac except on my home network at this point. Tho in all likelihood, the damage has been done, if it's going to be.
That said, I'm not particularly worried about personal consequences so much as potential work consequences.
I stopped using my work computer on non-work/home/mifi networks 2 years ago tho, and all traffic is vpn on it.
