I would add one more thing to your arguments: people who don't like ads should simply ask web devs of their favourite sites not to serve ads at all. Even if ads and trackers exist it is still ultimately the developers choice to include ad code in their websites. I sense A LOT of misdirected anger towards ad companies when the "enablers" of ad companies – the web developers willing to monetise traffic with ads – are not getting any blame directed at them. As long as you guys at Facebook are transparent about what happens if you embed your like buttons or comment sections in blogs and forums etc. the onus is on the developers to serve their visitors with safe content.
