You can't really blame Meta executives for wanting to limit the amount of political shouting on instagram and Threads. Those things can get pretty toxic. As a result, both Meta social networks now limit what Meta calls “political content” from people you don't follow.
However, if you are a Threads or instagram user and want To be exposed to posts “that are likely to mention governments, elections, or social issues that affect a group of people and/or society at large” (which is how Meta describes it), you can still do so by opting into political content. The only thing that might be a little confusing is that you have to sign up for the instagram app, even if you primarily use Threads.
And now you can expose yourself to as much political infighting as you want. The fact that you need to choose in to political opinions on a social network instead of choosing outside It may seem a bit backwards, but apparently this is the way Meta executives felt most secure. Whether this strategy will actually make Threads a less contentious place, or whether it will simply make it less interesting, remains to be seen.
