Agree, but limited and respectful advertisements given by Alphabet are a oximoron. FF don’t select the companies which recive the data from Alphabet, selected by user activity. That is the sense of surveillance advertisings, if you enter in a page to consult for a good Hotel, after this you’ll see advertisings of Hotels, travel agencies and other nearby to you, if you don’t block them. But all these companies know that you are searching a good Hotel. Do you know how these companies protect this data? You don’t, and this is the risk, in the worst case someone knows that you are planning a travel and you are out of your home a given day. In the past it had ocurred several times the filtering of user data, among them medical and banking data in this way. Surveilolance advertising is a crime, not a legitim manner to create incommings, less for a FOSS which claims with privacy.
