Google Analytics as well as Microsoft, which indeed makes "tech companies". What are you implying here really?

I get what you mean, but it's still perfectly accurate.

I thought the same thing but it's still not a good look. The big tech companies offering this sort of thing should probably find ways to give better guarantees about data isolation, even if that requires e.g. clients paying additional fees.

You say that like there's a difference. You say that like the detail of data that Google Analytics farms is acceptable. You say that like what Google does with the data is acceptable. Just because companies want the data doesn't mean they deserve it.
