@w4ts0n @Gargron the main argument against opt-in is that most people won't know about it and therefore very few posts will be able to be toot boosted and therefore the setting may languish and not have uptake, even among the many people who might be happy for their own toots to be toot boosted, if they knew they could enable it. People annoyed by the their toots being toot boosted are probably a lot more likely to chase down a solution.

That said, the privacy friendly way is to make it opt-in
