I've had two Twitter accounts for years, my main one @stormhighway (which I just deleted) and the other for @icyroadsafety (which I'm keeping for now but have not been active on it).
On the icyroadsafety one, I have been getting the "liked" tweets in my timeline for years. It was switched to algorithmic a long time ago with no option to go back. I always go through and select the "see less like this" thing, but it has never had any effect to this day.
The big thing that social media platforms have embraced is the "keep the user on the app" paradigm, which means no engagement for external links. That pretty much takes any end user benefit out of the picture. Instead of a viral photo generating print sales or a Youtube link generating some income, all monetary benefit is going to the platform now.
These companies have bigger advertising audience value than national television networks, yet they are getting more free content to keep their pockets lined than any TV network ever has. Years ago, you could post a photo or video link and get some traffic in return for the ad revenue you generated for the company. Now,, they've taken that away, and the momentum of everyone maintaining the practice of posting their prized photo and video content directly to the platform is giving them a windfall like no company has ever seen in history. And they share none of it with those who generate it.
