Yes, but taking a screenshot is not even close to being the same as scraping my data.

My problem is, I don’t fully understand how to defederate from it.

For example, if I subscribe to a community on an instance that isn’t defederate from Threads, and I post there, am I handing my data to Threads. I don’t understand where the line is at which my data is protected from Threads.

That is a serious problem for me that would make me stop using the fediverse.

It’s not a trick at all. They want personal users to use it on the chance they then introduce it to work.

They are a very positive company that supports the FOSS community. It is a great product.

No, it isn’t. But there is a self hosted Foss version of it (headscale) that the developers actively support.
