That's not remotely the same? A default setting that can easily be changed for a feature the vendor didn't have a solution for? To give you an example. Try to use Google Search without sending your data to Google. You cannot use the product without it, you cannot opt out. Firefox, you can use just fine with Google not being your search engine.
Why isn't it the same? The fact that it is possible to change that default means google simply pays less for it than they otherwise would if it wasn't changeable. It's not a binary toggle - firefox is selling you as a source of revenue for themselves. They're just not making it as extreme as it is possible to be - in the hopes that you don't switch away. You can compare same situation with safari in iOS. Except googl…
The sense in which you are the product on Firefox is that they want to maintain a large enough user base that search licensing is valuable enough to sell to Google.
