I found myself wondering the same thing. Do they genuinely expect people who have never heard about FSFE to be using a decentralized social platform? That sounds scary. Normal people don't use scary sounding things.
They're certainly welcome to do whatever they think is right, and it sounds more "on brand" for them, but it seems ridiculous to say something like "[Using Twitter was] important for reaching members of society who were not active in our preferred spaces for interaction." but then end with "Follow the FSFE on Mastodon and Peertube!" I am very tech literate and I've never even heard of Peertube. There is very little chance they are ever going to reach even a single set of ears this way.
At that point, they might as well just send random fliers in the mail to strangers.
