There is also an argument to be made that adblocking is immoral. I think the idea is pervasive enough to fill a team of willing people, especially if you pay them 100k/year to at least go along with it for the time being
I haven't made up my own mind about it yet, just that this might be a factor in why one would move the facilitating technology backwards in this way (and forwards in other ways, apparently: some people in the thread are reporting that uBlock Lite is faster. Not that I can tell the difference between a clean Firefox without add-ons (I regularly use that for work reasons) and a Firefox with uBlock Origin (my daily driver) except if the page is bogged down from all the ads)
