The whole point of Bluesky is to build a social network that is not incentivized by advertising. They don’t rule it out completely, but it can’t be a major part of their revenue.

This reads as definitive to me personally.

Neither of those is the same as "no ads". They're just saying that they can't make the ads so bad that most people want to leave, because then people will leave and the ads won't be shown to anyone.
Bluesky doesn't have the ability to do this. There's no API key to revoke that could stop someone else from running parallel apps/infrastructure/etc. The network is completely open.
I'm about as anti-ads as it gets but I don't object to other people using apps with ads in them, if that's their choice.
