Since Meta Platforms' stock is highly liquid, it does not matter much (except maybe for computing taxes) whether Meta sells stock and gives 100M in cash to the employee or gives the employee stock, which the employee then converts into cash.

In either case, the fact that the stock was created is reported to investors, and investors know that the creation reduces the value of every existing share of Meta, which is the feedback mechanism which restricts how much money or value Meta can get out of the creation of new shares of its stock.
