My opinion is that, this is the world now.
There are dozens of reasons why requests would be sent to Apple or Google for autocomplete reasons, as veen quoted from a HN comment. There are also reasons why companies want your personal info for marketing and data collection and other "nefarious" reasons, as some would put them.
My opinion - which you don't need to agree with, or care about, but since you commented I guess you do care - is that this is how it is now. If you want to use Google products and Apple products and Microsoft products and <insert_name_here> products, you can expect to share some (if not all) of your personal data with them. I'm not saying it's right or wrong (and in fact, believe it's not a 'right' or 'wrong' thing generally), I'm saying that's how it is.
If you don't want to deal with this particular evolution of the social contract, then you can opt out. Go get tor and run it behind a VPN if you want to go that extra mile. Turn off all of the scripting and functionality that makes the web a little easier to use for the sake of added privacy. Go to it, that's your choice.
All that said, mk's note about a law to advise people on data collection is just fine and a pretty good idea.
That's my opinion, and it's all the backing up I have to do, because it's mine, and frankly I don't care if you agree or don't agree. You can always go to my page and filter me out.
But you need to calm down. Your worldview that everything has a side is wrong. Not everything does have a right or wrong, and not everything has a side A and side B. I don't have to choose a side, because there isn't a side to choose.
I posted because I felt like posting. Don't like it? Move along, nothing to see here. No one's going to stand over your shoulder and make you read my opinions on the internet, I promise.
