According to a report from The Platformer, Amazon Inc is preparing to restart its advertising on Twitter, after a small kerfuffle with the platform’s new owner, billionaire Tesla CEO Elon Musk.

The fight began over Apple threatening to pull the Twitter app from its App Store, which would have in essence prevented the 125 million iPhone users in the United States and the 1.2 billion users globally from using the Twitter platform.

Musk quickly took the fight to Twitter, tweeting directly at Apple CEO Tim Cook. The tweets rapidly moved into the fact Apple had ceased advertising on Twitter, presumably as a protest of Elon Musk’s takeover of the company, before moving on to questions over censorship of other apps on the App Store platform by Apple. It then segued into a broader criticism of Apple’s pricing model, referring to the 30% of a developer’s profits off an app, which Apple demands in order to be sold in the App Store, as a secret internet tax, placed on everyone’s App Store purchases.

On Wednesday, Musk visited Apple’s headquarters to meet with Tim Cook. Musk later tweeted he had worked out his differences with Cook and the Twitter App would not be banned from the App Store.

Now Apple will resume its advertisements on the platform, with a spend of approximately $100 million per year. It is presently waiting for some reported security tweaks to Twitter’s ad platform, before resuming its spend.

Musk also announced the return of Apple to Twitter’s advertising client stable in comments made during a Twitter Spaces conversation Saturday.

Apple does not disclose the amount or placement of its ad spends, however Musk has referred to Apple as Twitter’s largest advertiser, and it is believed the announced spend is comparable to what Apple had spent under Twitter’s previous leadership.
