Both bans have now been suspended.
Lewis said Walmart is hoping some of those eyeballs will now buy stuff at Walmart's online store, a gamble aimed at giving Amazon a run for its money.
The filing, published by CourtListener, reveals the judge considers the USA government "does not meaningfully contest through evidence" the effect of preventing WeChat business transactions on WeChat users in the United States, even when taking into account the "overarching national-security interest".
He regularly accuses Democratic opponent Joe Biden of weakness toward Beijing.
While Oracle has the authority to check the source code of TikTok in the US, ByteDance said displaying the source code is a way for multinationals to allay local data security concerns.
A suspension of the ban on new downloads of WeChat comes after the U.S. government delayed a similar ban on downloads of TikTok after the app's parent company announced a deal with Oracle.
ByteDance quibbled with the announcement by Oracle and Walmart that it would pay more than $5 billion in new taxes to the U.S. Treasury, saying the number was not finalized.
In response, the US Department of Commerce delayed its implementation of a ban on new downloads of TikTok to September 27 from its original date of September 20. On Saturday, he said he supported in principle a deal that would allow TikTok to continue to operate in the US.
WeChat is "mostly used by Chinese visiting or working here or by Chinese-Americans staying in touch with their relatives", said William Reinsch of the Center for Strategic and International Studies in Washington. Oracle will now house all of the United States user data to ensure that nothing nefarious happens to it, though security breaches are still very much possible at this point in time. These export restrictions included "personalized information recommendation service technology based on data analysis", which industry experts saw as a nod to TikTok.

"But on this record - while the government has established that China's activities raise significant national security concerns - it has put in scant little evidence that its effective ban of WeChat for all USA users addresses those concerns".
On Friday, it was listed by the US Commerce Department to be barred from mobile app libraries and access to essential internet services in the US.
United States officials have described Washington's crackdown as essential to safeguard against potential Chinese espionage through the platforms.
Speaking at the White House on Saturday, the U.S. president said he approved of the proposals, having previously ordered TikTok to be banned in the USA over national security concerns.
