Who says that Meta is not already harvesting our data? Lemmy really is about moving control out of corporate hands and decentralisation advantages, but profiling is insanely easy on the Fediverse, and it really cannot be different because of its inherent interconnectedness. It makes no sense to migrate from conventional social media to Fediverse equivalents if all one cares about is privacy.

How do you know that meta hasn't created an account on a popular well federated server and it's using those credentials to scrape the fetiverse?

You have to assume whatever your post to the Internet is available to anyone and everyone connected. Why would federated servers be and different.

Everything is public on fedi (if we're talking about communities alike), so any bot can and is already scrapping everything through regular HTTP. You must be extremely ignorant to think otherwise.

Meta can collect every scrap of Lemmy right now

Edit: downvote for what? My comment is true
