The link goes to this users Mastodon post on the subject. I'm going to copy part of the text of his post without having to post the Threads post they were shown. Click through if you want to see for yourself, avoid if such things are upsetting to you.
"This was a post promoted to me from within Instagram to try and get me to use threads. Ill say that again: this is the promotional content shown to non-threads users as an inducement to join threads."
If you do click through to the Mastodon thread, you'll see several other people confirming they've seen the same or similar posts promoting Threads.
I've said the same thing in comments to other Threads related posts in this community but I'm going to say it again; didn't we create and use fediverse software like Mastodon, Lemmy, PixelFed etc in large part to escape the constant hate-baiting and algorithmic manipulation of companies like Meta? Why are so many in the fediverse prepared to throw their fellow fediverse users under the bus by exposing them to a company and a set of users who not only say these things and not only allow them to be said but actually use them as a promotional tool to encourage more people onto Threads?
If Threads was a fediverse instance, it would've been defederated from by just about everyone by now. Why are some people bending over backwards to give Meta a free pass?
'Wait and see' I hear people say. I can already see.
We all knew this will happen then you can take preventive measures or not. I always think preventing os a better option with lower cost.
Now, people have to act otherwise they are supporting these views. The fediverse is a safe space for many minorities. You may not be part of one of them but the fediverse doesn't work like other social media. You don't have one parent company to take in account. You are accountable or at least the instance you're on. This is due to federation.
People have to change their mind on this too. We have to change this rule. We have to move more like one. This can be called unionizing. People and instance have to unionize to keep the leadership in social media. This will be a non individual response to the issues. We look collectively at them with tolerance as a common contract.
This is the opposite of how these companies like meta work. They want to put the responsibility on the individual as always. They grow their capital from this by exploiting the cognitive free work of the user. It's completely individual and the algorithms help to push this logic at the extrem. By thinking, the fediverse should not have a common response, people are playing the game of these companies.
This is why we have to change and unionize, to have a peaceful place where we put the common first and reject the individualism. We can show people that a better place with different rules than what we see for now 40 years is possible online.
