I run a pie hole, it has a lot of meta/facebook subdomains blocked. I would recommend that as a simpler potential solution than flashing custom firmware.
Meh. I like the honesty and the input. I'm considering a quest 3, but I also hate that meta is the one putting it out there. I'll probably justify the purchase by telling myself that they lose a ton of money on every unit and are just trying to buy market share.
