Booz Allen is not renting us a park, because they don't own it, hence they cannot rent it out. Booz Allen is running a website and we are paying them fees because that's the money they use to run the website. He quotes them as saying as much in the article.
Then he goes on to basically state he has no clue what they were paid to run the website, and yet the entire article claims that the fees are "junk", regardless of the fact that he has no evidence to support this.
Despite this, in the linked article on Booze's website it states: "With more than 45 million users in FY21, the site has generated more than $270 million in revenue for the federal government". Compare that to the 182 Million to be invested in Booze over 10 years (18.2 Million/year averaged).
It's not stated how payment takes place, but Booze's wording suggests that the government did not have to front the capital and instead Booze will recoup it over time, which takes the risk off the government of another $400M boondoggle.
Clearly the government is making more money than it is spending, which is what you want, rather than a botched government job spending $400 Million and having jack shit to show for it. Not only that, but Booze's site was completed in only a year, and was the first major government site made in the cloud. It has continued to expand and has not failed. This is an amazing achievement for government work.
Pay them your fees and stop whining, or we'll end up with the government failing to make a basic website for 10x the amount of taxpayer money. People love to whine when they have to personally pay a fee, but they don't care at all when their taxpayer dollars are flushed down the toilet in the millions to billions. Out of sight, out of mind.
