I don't allow tracking or advertising at all, whether from Internet services or local radio and TV (mostly do not use ad-supported stations), never had a Facebook/Twitter/etc., account, not used Google for the last decade, and so on.
However, in exchange for avoiding tracking and adverts, I actively pay for services I appreciate in whatever way they provide for whether through purchase, subscription, or donation.
I really wish Mozilla Corporation would have a DONATE TO FIREFOX option* to directly support development of the browser (and Thunderbird) and a max-privacy version. This would directly quantify real support from those like me that object to tracking and/or invasive adverts - I suspect the amount raised would be minimal, but it'd put the default search engine funding into perspective.
Not a lot of people realise that donating to the Mozilla Foundation does NOT support Firefox development by Mozilla Corporation.
* I was one of those that paid for Netscape Navigator back in the mid 1990s before Microsoft released Internet Explorer as part of the Windows OS and wiped out the paid-for browser market and forced Netscape Navigator to be released free of charge in order to try to compete - which directly led to Mozilla and Firefox.
