One thing that has certainly changed is that algorithms have become more aggressive. If your content isn't performing well, it gets hidden much faster and more aggressively than before. This makes sense when you consider it from the PoV of the platforms (they have much more content to choose from)
Not saying it's working, but I believe something like that is their current design intent of that joke of a massive backwards revolver. The way it currently works is that only those smart enough to bypass the penalization wins.
EFF reps on Twitter probably aren't "smart enough" to game that system, so they stay in the tiny group, and therefore they won't get the views.
The EFF is at odds with both facets of the current US administration as well as the big corporate donors in its pockets and its posts deal with nuanced topics, and so naturally its posts are among those not surfaced as often.
A decade ago they lost the plot. They pulled some bullshit and lied to their entire membership in order to boost their cronies/friends at the Library of Congress. They framed efforts to keep the LoC under loose Congressional/Presidential oversight and free to do as they want as some Anti-Trump fight. Requests about why they would do this went completely unanswered to the membership.
The EFF Board serves their own goals and believe themselves unaccountable to their membership, so they no longer get my money and I no longer entertain or signal boost their message.
