So people can't click a share button? When your post gets published, hit the share button. You don't need an automatic thing.

Things cost money, running Twitter/Instagram/Facebook/WordPress/etc... costs money to run. Yeah, let's blame Musk, the end of the world is here. Let's all move to Mastodon.

All the instances of Mastodon, I can't remember seeing any advertising. There are three ways to fund things: (1) ask for donations (2) advertising (3) charge for a pro version. Most wp plugins do 3 by the way.

Yoast SEO does pro, others do freemius thing.

Advertising has gone down for years. Most people won't even donate.

You do not need JetPack publishing, I personally don't use it. I use WP to Twitter. I am debating removing it from my sites.

Twitter is a private company now and can set their own rules. Musk is not a bully.
