It is getting to the point where the sites demand that you give the full access or you will not be able to use them.
I used Flightradar24 for many years and recently I was getting ads in Russian and all kinds of cookies. I finally stopped giving them access and stopped using it. That is also true with some acft sale sites, you will not be able to see the pics, just the text, unless you give them full access.
If you look closely you see that many sites will direct your IP to Google sites before you can log in, it just seems that there is no way to protect your privacy / yourself on the Inet anymore, unless you want to stop using it.
What I do is just use a tablet without any real personal data on it, to use the Inet for certain sites.
