After seeing AOC's post I feel Twitter should be banned. Until that happens there are things we can do that are simple and effective:
For people who have a Twitter account:
Switch to Bluesky and make a Tweet saying you are now on Bluesky and no longer post on Twitter. Note that per Furball's comment if you use the word Bluesky in your Tweet it will be hidden. Be sure to censor the word or use a screenshot.
If you have no choice but to use Twitter install an adblocker such as uBlock Origin. Also review your privacy settings.
Leave a 1 star review on the app store for the "X" (Twitter) app.
Things everyone can do even if you don't have a Twitter account:
Help your friends who are still on Twitter migrate away.
Urge companies, governments, organizations, celebrities and other large accounts to make a Bluesky account and phase out the use of Twitter. They can start by posting on both to make the migration easier.
If you're writing an article or posting on Lemmy, Reddit or other websites prefer linking and screenshooting Twitter alternatives such as Bluesky, Mastodon and Threads instead of Twitter when possible. This is also good for your readers because Twitter makes it hard to read Tweets without logging in.
Contact people in your government and urge Twitter be banned.
I don't think the government has the power to ban twitter, and it probably shouldn't. But individual users should stop using it.
Unfortunately, people are emotional little bags of shit and just want to see their funny memes.
This is why we can't have nice things. Too many people are basically toddlers and cannot delay gratification.
On the other hand, the government probably could have Musk killed. That's kind of scary and I don't really want to have a government that would do that, but do I want that asshole to die.
Gotta love President Musk's brave defence of free speech just make sure you don't want to share a link, mention any competitors, use the word cisgender, or track his private jets
Brazil banned it for roughly a month earlier this year, but that was due to the company deciding to ignore the law and refusing to pay fines.
No idea about USA, but other countries could claim it's being used to spy on their citizens, much like USA is accusing tiktok.
The other way to ask for a country wide ban is to make a very, very, very strong case for how much the disinfo spread through there is harmful for the stability of the country. Then again, you'd have to apply that to whatsapp and telegram as well, there are thousands of groups that are all about sharing rage bullshit
Did I say it has been banned? No, I said that it is being banned, meaning still in the process. That is unless the owning entity sells it to another company that doesn't have significant foreign government controls.
