The algorithmic stuff was only ever for users' feeds, not Twitter profiles.
It's made the whole business of status updates completely unusable. If I want to find out why the fire helicopters are out, I can no longer see that on the fire department's Twitter page (even though they do post it!). If I want to find out if my local lake is closed due to algae, I can no longer see it on the park's page (even though they do post it!).
Pretty soon all these organizations are going to realize that their pages are worthless and leave Twitter.
a) Favouring blue-tick comments and post over those with higher engagement.
b) Paying people to comment which has meant more click-bait, hate etc. content.
I don't think this is a very fair and honest take on the toilet flush spiral where Elon Musk placed Twitter. Screwing up the timeline made available to non-registered users is a recent development, and one that lands squarely on Elon Musk's rule over Twitter. So does the shitshow that was the verified badge policy changes and opening the floodgates to racist and anti-semitic content.
In fact, I dare say that there was not a single change to Twitter that spawned from Elon Musk's takeover that had any positive or neutral impact on the company in general and service in particular.
