If you've ever wondered where your crazy uncle gets the topics he likes to bring up at the family dinner table, you might need to look no further than Parler.

The app's users pride themselves on being able to say pretty much anything they want.

And back in January, Parler's users were saying certain things about election fraud, certain things that might have played a role in fomenting the Capitol Hill riots.

And whatever the case, Amazon (AMZN  ) , Google (GOOGL  ), and Apple (AAPL  ) decided that Parler's no-holds-barred approach to content moderation was in breach of their terms of service. And since then, the app has essentially gone dark, hanging by a thread in obscurity at a Russian server farm, and only accessible to Android users through a backdoor.

But on Monday, things changed when Parler ended its months-long exile from the Apple App Store.

Although, the App Store version of Parler has since been dubbed "Parler Lite" by the Washington Post. In short, iPhone users will have access to a different version of the app. A version in which potentially hateful or violent content will be automatically screened out. Parler's Android users meanwhile get an app with no such limitations.

According to a letter Apple sent to U.S. lawmakers, both sides have been engaged in "substantial conversations" in the many months leading up to the reinstatement.

"Parler has and will always be a place where people can engage in the free exchange of ideas," said the companies interim CEO Mark Meckler on Monday, quoted by the Wall Street Journal. "The entire Parler team has worked hard to address Apple's concerns without compromising our core mission."

Before the Capitol Hill riots, Parler had billed itself as a place where people could speak freely, in the most literal sense of the term. According to Parler, its users didn't face the risk of being "deplatformed" by seemingly overzealous moderators. Anything was allowed, provided it wasn't "criminal." Community guidelines were made up on the fly, and what little moderation there was, was performed by a group of volunteers, which included the companies then CEO John Matze.

After the election, when Facebook and Twitter began to censor content concerning potential voter fraud Parler's fragile moderation system broke down under the strain of new users hoping to discuss their latest theories.

And the rest, they say, is history.

Since its fall from grace, Parler has been resurrected to a lukewarm reception. The app has lost roughly 18 million active users since it went dark earlier this year. Hoping to restore its fortunes, Parler is currently competing with other "free-speech" social media alternatives, like CloutHub and FreeSpace, for the privilege of hosting former President Donald Trump's social media accounts.

Mr. Trump has been looking for a new platform since he was booted off Facebook and Twitter earlier this year. Although, the former president has said that any option he chooses will have to be "indestructible." Unfortunately for Parler, the aforementioned events have proven that their app is anything but.

Parler claims its App Store version will be "viewpoint neutral" and that the app won't be used to incite violent outbursts like what occurred on January 6.

Nevertheless, Parler's place on the App Store is by no means secure. Companies with far deeper pockets have tried moderating people who are likely far less raucous than Parler's key demographic, and they have barely succeeded. Parler will have to do better than either Twitter (TWTR  ) or Facebook (FB  ) to remain in Apple's good graces.

Whether it can do so remains to be seen.
