Even if getting to orbit is free, the numbers don’t work.

5 years is a standard depreciation cycle for hardware, but plenty of machines last longer than that, but these satellites will not. On top of that, power distribution, cooling etc in the data centers is a huge percentage of cost and lasts much longer than 5 years.

If you think you can make a space air conditioner for less than a terrestrial one, I have a bridge to sell you.
