In many ways, Mastodon feels like rewinding the clock on social media back to the early days of Twitter and Facebook. On the consume side, that means that your home feed has no algorithm (this can be disorienting at first).
Practically, it means that you see only what you want to see and only see it linearly. You never wonder “why am I seeing this and how do I make it go away?”. Content can only enter your home feed via your followed tags or handles and the feed is linear like the early days of social media.
It would take some adjustment, but ads and data harvesting are the core problem to the enshiftification of the entire internet. You can’t have it both ways. We have this endless game of cat and mouse where we keep moving to the next platform after the last one becomes unusable due to ads and data harvesting.
You have to draw the line somewhere to end this pointless cycle and it is either pay for software and services or have people do only what they want to when they want to (FOSS). It really doesn’t cost that much if it isn’t attempting to compete with other software that grew with ad and data harvesting money.
