As news swirled Monday that Elon Musk would close a deal to buy Twitter (TWTR) for $43 billion or $54.20 a share, some users of the social media platform have been quick to turn against the potential new owner by calling for a boycott of the site.

Many users of Twitter have said they would leave the platform if Musk’s bid was approved.

Shares of Twitter were up near 4% mid-day Monday upon the news that a deal with Musk could finalize that day.

The Wall Street Journal reported that the parties had worked through the night to hash out a deal as Twitter warmed to Musk’s offer after he disclosed he had secured $46.5 billion in financing, but sources for the news outlet said there were no guarantees they would reach one.

But some users of Twitter seemed lukewarm to the idea of Musk heading the social site as many said they would abandon the platform and close their accounts if the Tesla CEO bought it.

But not everyone agreed as some welcomed the idea of Musk buying Twitter.

As of Monday at 12:28 p.m. ET, shares of Twitter were trading at $50.75, up $1.82 or 3.72%.
