When the board triggers this clause, they may sell shares to existing shareholders at a discount. These are new shares. Companies have every right to sell shares outside of the exchange they’re listed on… and they do that all the time, through employee grants or options, for example.
When raising funds they generally sell new shares on the exchange, because that’s the highest price they can obtain for the share.. but they don’t have to do that.
And yes, in case you didn’t know, companies can sell as many shares as they want.
A company cannot issue unlimited shares without concern for existing shareholders - taken to the extreme, doing so reduces the value of all holdings to zero.
For example, if Elon goes to 16% ownership why doesn’t the board just distribute new shares to existing owners pro-rata to the point where Elon is back to 15%?
All of this seems pretty sketchy to me. I don’t see how the board is legally allowed to do this.
But it can sell shares to some and not others [1]. (This was a landmark decision [2].)

Having the board ignore a large shareholder would be one thing. Shares give votes, and terms don't turn over every day, and we don't kick out politicians as soon as the polls turn sour on them. Fine. But if a shareholder has enough shares to change the board composition (or just threatens to) the incumbents can just unilaterally decide that the challenger owns a smaller fraction of the company than they bought on the open market? Maybe it's not technically self-dealing, but it's bad.
Now, you may argue that it is in the best interest of the shareholders to allow the hostile takeover to go through, but it appears that the strict mechanics of the poison pill do not immediately hurt shareholders.
There are many varieties of poison pills [1].

If you've ever wondered why corporations have authorized and issued shares, there you go. Increasing the authorized share count requires a shareholder vote. Issuing shares under that cap does not. When shareholders increase the number of authorized shares, they are delegating that decision making to the Board.
It wasn't always like this. But as finance sped up, particularly towards the end of the 19th century, a railroad company which had to hold a shareholder vote to raise emergency equity because their free banking deposits in Nevada went bust would find itself systematically outmaneuvered by the ones who had pre-approval to plug the hole. As a result, most corporations now authorize the maximum number of shares reasonably possible, in almost all cases only moderated by some states' franchise taxes varying by number of shares.
Wikipedia of Shareholder's Rights Plan is skimp in details as well.
Everything I hear ostensibly appears to be "That should be illegal, makes zero sense". So with no good information out there, it seems like no one is an expert at this and making up bullshit.
If I issue more stocks for a meme stock at the height of it's popularity it will likely go up in price for reasons completely disconnected from the balance sheets and future revenue.
Conversely, if I recently started the process for bankruptcy and issue more stocks to cover the liabilities on my balance sheet, the stock could very well decrease disproportionately to the number of issued stocks.
Stocks at the end of the day are based on the market's perception of the stock's worth. The market is not a single rational actor, rather numerous small irrational actors and a few very large highly rational actors. Obviously there is a spectrum in between, but the ratio of buyers on a given end of the spectrum will influence the behavior of a stock to either align or diverge from the fundamentals of the company, and not always in the way you would intuitively expect.
Imagine there are 1000 shares and Elon got 150 of them, bought at $50 so he owns 15%. If the board now sells 1000 new shares to people who aren't Elon, he now only owns 7.5%.
It's not that you resell to the board
So it’s a question of balance. Twitter can raise the fundamental value of Twitter a little bit but there’s no way they can raise it too much without driving the price down and then just having more shares available at lower prices, so like you could just buy 2 shares and spend the same amount of money.
The US legal system is kind of based around this adversarial situation imo.
