The arguments I've heard about tracking etc are misguided and don't understand the actual risks.
Firstly, posts on the fediverse are already likely being consumed by advertising platforms like Facebook & Google. It would be trivial for big tech companies to setup relays that act as scrapers.
Secondly, the value in platform's tracking individuals is for advertising. There is no mechanism for these platforms to identify you browsing the we if your instance federated with threads. Your instance won't share cookie sessions etc with threads. It doesn't increase your exposure.
Thirdly, these platforms have the know how to deal with spam and they will be incentivised to share that tech with other federated instances.
Don't get me wrong, Facebook is an evil company. But I haven't heard a decent argument as to why them joining the fediverse is a bad thing. We always have the option to defederate in the future.
Change my mind.
No amount of extension will force instances to change. I think your point assumes instance owners will want to have access to those users from threads for some reason.
I would only be worried about the EEE thing if meta assigned a team of developers to work on the Lemmy codebase full time.
Meta has blown 10's of Billions on the their failed metaverse and you're wondering if they will have a team of devs on Lemmy? They already do - it will start with the protocol first, not the UI, but you'll start seeing PRs there too.
You're probably right, we need to borrow the Linux model with some ahole at the top cutting out crap before it takes over.
No offense Linus, love your work.
