Last decade, some companies (that had more money that they knew what to do with) used that money to buy shares back. This decade, this company (that has more money that they know what to do with) invests in either "AI" or "AI datacenter" companies — and these use that money to buy the company products.
A company buying back shares is spending money to purchase an asset on the open market.
A company involved in round tripping passes fictional money in a circle and every company that touches it claims both revenue and expenses simply for passing it along.
