PS. I should also mention that my data shows clear evidence of algorithmic changes on Facebook (Fall 2018), X (Fall 2022 and ongoing) and now Threads (Nov 2024) explicitly downweighting climate content.

In Aug 2018, 'clean energy' was added to FB's "socially sensitive topics" list, and my page's growth was cut in half. A few months later, 'climate change' was added. My page growth froze at 46k then decreased, and my engagement dropped about 10x.

Now, changes in the Threads algorithm made in November have similarly frozen my Threads account and tanked engagement there as well. Here's the data below.
