So, now that X is banned in Brazil, which other apps do Brazilians fall back to? Will X regain its prime position as a social hub in the region if Brazilian authorities may lift the ban at some point?

In brief, Brazilian officials outlaw X outright after the company fails to quell the spread of damaging misinformation in the platform at the start of this month.
Brazilian officials had called on X to censor a set of accounts that have been persistent enough to challenge the validity of the outcome of the 2022 election. X refused and since closed its Brazilian local office for fear that any X staff will be arrested for defying the order. The absence of a local representative violates Brazil's rules of operation, and hence, the X ban was promulgated as a result of X's act.

X reportedly had around 22 million daily active users in Brazil, or around 10% of the local population, though as with most regions, X's influence is generally greater than its usage figures in themselves.

So where are those 22 million people now engaging instead?

Well, a Twitter alternative platform created by former employees of the company, Bluesky, has added 3 million more users over the last week, or 50% growth in its user base since X banned this.

Much of that growth has occurred in Brazil, where it briefly topped the iPhone "Free" app charts, before being knocked out by X's other major competitor in the region, in Meta's Threads.
Threads' download ranking has also leaped in the region in the wake of the ban, with Elon Musk essentially giving Meta an open door to scoop up more users via the ban.

But still, Musk keeps repeating the lie that X is still super popular in Brazil, based on the rankings of the "News" app.
Which is misleading, inasmuch as X is never going to be a news app, and never has been, and only is listed as a news app on iOS because former Twitter management were sick of being negatively compared to the growth of Facebook and Instagram, in terms of active users.

For comparison, the top actual news app in the above listing, Brazil's "O Trabalhador", has fewer than a million total active installs, so it's not exactly a competitor on this count.

But Elon and Co. are keen to re-angle the company's defiance of the Brazilian order as a battle for free speech. Which, in some ways, it is, in terms of allowing alternative political perspectives to be heard. At the same time, however, the unrest that flare up with every single raised question about the validity of the electoral process of the nation caused already grievous harm, and will continue to sully tension within the region as they head into the next elections.
Therefore, it would have been expected that Brazilian authorities would be eager to quash this to avoid further influences and, especially now that you include in that consideration also that all investigations made so far have shown no proof of any illegal voter manipulation, as those who think that the former President Jair Bolsonaro was unfairly voted out in the 2022 poll claimed.

So, is X coming back to Brazil anytime soon?

It cannot be so, as Musk continues to be severe on Brazil's ruling bodies, despite his other company, Starlink, having made some concessions in order to be able to continue their operations in the region.

Which, in fact, brings one to the crux of the deeper opposition from Brazil's ruling by Musk.

While Bolsonaro was in power, plans were initiated to further cement Musk's business relationship with Brazil in furthering to fortify the mining of lithium in Brazil and better pricing of the resource for Tesla as it uses lithium for its cars.

And that deal involved Musk agreeing to expand Starlink's program in the region as part of that wider arrangement. But when Bolsonaro lost the vote, Elon also lost big time on that initial investment.

Which is why he is really incensed at the Brazilian government, and now he looks set to cost X more money as a result of his own grievance.

Therefore, I'm not likely to put my money on the chances of Musk reaching a deal with Brazil's authorities anytime soon, and that would mean X is not going anywhere in the country for now.
