The entire argument boils down to "i think they're going to force data collection" vs. "I don't think they're going to force data collection" and Firefox has a long, healthy track record of not forcing their users to do stuff.
This whole debacle has been brought to the fore by Manifest V3 and at least part of this is driven by the desire to ensure that users will still have effective adblockers once that standard is the norm. In a very roundabout way, this conversation is happening because mozilla wants to make sure people will have an option for an adblocker. but they are ALSO hoping to improve protection for people on browsers that won't allow adblockers.
Like, you can see how, if this works as a product that does not track your specific activity and includes activity data in anonymized datasets, we would actually want companies like Google and Facebook to adopt this technology, right?
Facebook and Google are not going to work on finding a less-stalking way to stalk their users, there is no incentive for it that outweighs the cost of development. But if a nonprofit company takes the cost burden of doing the research, companies like Google and Facebook have enough regulations to contend with that they would have a much stronger incentive to adopt an existing technology.
