No, Twitter is not moving to monthly subs for access.
Musk said he would step down as CEO, he did. He said he would rename Twitter to the monstrosity "X", and he did. I don't believe him very often but this might be one of the times he stands by his word.
Maybe he should spend some time testing features to see if they have the results he expects before implementing them on a whim.
Though, on the other hand, I think he is right in that a subscription fee would probably end bots, for the simple reason that it will end the platform itself.
It's a bit of a shame though, I wonder where the OF creators will go; maybe back to Tumblr?
He figured it would be the celebrities rushing to do it first, but it turned out the first ones were the jerks. Celebrities are already a draw to the service; asking them to pay for the privilege of bringing customers (even a token amount) was unacceptable.
The jerks, however -- the ones who were desperate to be heard and would jump at a chance to pay to look better -- were happy to pay. Then users went out of their way to avoid blue-checks.
I suppose it's hard to test public reaction before deploying. People are unpredictable. I sure didn't anticipate that a service whose model was "a constant stream of inanities" would get billions of users. So maybe I'm not the one to ask.
But it sure doesn't sound like Musk has any understanding of why it's popular, either.
