For me, after @StefanKarpinski 's explanation about how lawyers see the IP issue, it seems reasonable to me. There could be a remark regarding the IP adress in the https://julialang.org/legal/data/ but all in all, it doesn’t look wrong to me and I am pretty sure that it helps a lot to improve Julia.
What exactly do you think is wrong? That it isn’t opt-in, just opt-out? As there is no personal data I would say opt-in is really not necessary. Looking at the data it is hard to imagine how this could be abused. And it seems quite minimal, which should be like that, no unnecessary data as far as I can tell.
