If you read the page it's pretty round about to get there though. It's buried in the last line of the description:
> P.S. — Proceeds from this campaign will be used to buy a controlling share of Twitter. If we can't get a majority interest, we'll explore options for buying a significant stake in the company and champion this proposal at the annual shareholder meeting. If that's impossible for any reason or if there is a surplus from this campaign, 100% of the balance of proceeds will be donated to Global Zero, a nonprofit organization leading the resistance to nuclear war.
So the whole thing is a marketing gimmick by Plame. Shocker!
> In an emailed statement sent to news outlets earlier today, [White House spokesperson Sarah Huckabee Sanders] called Wilson’s endeavor “ridiculous,” and suggested the shortage of funding for Wilson’s idea underscores that Americans are satisfied with Trump’s Twitter use.
Sigh. Because everyone who disagrees with Trump's Twitter use would donate to her cause...
