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.
I always find screenshots from apps confusing. Also I don't use IG. What is the context of these text boxes? Who is "promoting" the posts? It sounds like an ad from the user who posted it, but the accompanying text says it is advertising Threads.
I notice that the image posted here and the one in the comments by @wolfshadowheart have the same content but the usernames are different. Are they mirror accounts?
The screenshot is taken by an Instagram user. It shows an area of the screen Instagram uses to promote Threads to Instagram users by showing them Threads content.
It's not the users Instagram content that is shown but the post Meta are using to promote Threads to Instagram users, that's why it's the same. Lots of users are (or were) seeing it.
Yes, I am both averyminya@beehaw.org and wolfshadowheart@slrpnk.net - I had to post the image from my slrpnk account due to Beehaw not having image uploads supported on my app. I just initially saw this post on Beehaw, so I commented to not lose it.
My screenshot is taken from instagram, it's just one of the random "promoted Threads" posts that pops up as you scroll randomly. If you like, I can post the uncropped image as well. I initially posted it, but then removed it since it was just a busy screenshot, not necessarily because of any personal info of mine of the accounts I follow.
