It is relevant because IT projects are inherently difficult, and many of them fail. Just because the French government failed at two projects mentioned in the original comment does not mean that a) it's particularly bad at IT projects or b) it will necessarily fail again. Having the corporate failure rate as a baseline could help assess the proficiency of governments around the world.

It is if the grandparent meant to disparage government IT projects (compared to corporate IT projects) -- which is a possible reading.

(It's also relevant because because we pay corporations with subsidies, tax cuts, tax evasion, research grants, public procurement, specialty laws favoring them, etc -- sometimes even more than we pay governments).
