well… you make a point that everything that you post on the internet is “public” in a sense, but there’s a pretty big difference in the effort required to scape it and providing direct API access to the data source which gives Meta access to much more than simply the contents of a post.

think of it as the difference of bing able to get a blood donation and sticking an IV directly into another person’s (or, in this case, anyone’s and everyone’s) artery, unfiltered, anytime, every time, on-demand, and without permission. forever.

no thanks!

one important distinction before I answer your question: Threads in a product of Instagram, not Facebook, and, although all are owned by Meta, each are run independently… but their business practices - and, thusly, their collective interests/goals/methods in and of data harvesting - are the same: invasive, exploitative, and, revolting.

Will facebook be able to create dummy instances that would federate with the large/established instances and take our information?

that’s exactly what Threads IS: a new Meta-owned service based on the same federated service that runs Mastodon and Lemmy (ActivityPub) and intermingles content and data from those services’ instances, and hence the widespread calls to defederate from it. so, it seems that you’re, at least, starting to get it. The calls to defederate (block) Threads is in the interest of keeping our data out of Meta’s hands. This would also mean we won’t see their content, but most people here don’t want to see that here anyway (or, at least, would rater keep the two separate).

edit: it’s also an example of Meta’s (and other large tech company’s) practice of Embrace, Extend, Extinguish with regards to emerging, independent technologies which they see as a threat to their control and profitability in the market(s) they control.

"Embrace, extend, and extinguish" (EEE),[1] also known as "embrace, extend, and exterminate",[2] is a phrase that the U.S. Department of Justice found[3] that was used internally by Microsoft[4] to describe its strategy for entering product categories involving widely used standards, extending those standards with proprietary capabilities, and then using those differences in order to strongly disadvantage its competitors.

The strategy's three phases are:[12][13]

• Embrace: Development of software substantially compatible with a competing product, or implementing a public standard.
• Extend: Addition and promotion of features not supported by the competing product or part of the standard, creating interoperability problems for customers who try to use the "simple" standard.
• Extinguish: When extensions become a de facto standard because of their dominant market share, they marginalize competitors that do not or cannot support the new extensions.

Meta wishes to establish Threads as the new “standard” of the Fediverse which is antithetical to the entire concept of the Fediverse, which is to resist centralized, corporate control of the platform and to remain independent, open-source, and free.

any more questions?
