Much of what you say is true, but doesn't negate the point of the comment you are assuming the motivation of.

The UK national infrastructure does have a history of dubious at best procurement, outsourcing and "consultancy" decisions in supplying it's services - those public services often then coming under extreme criticism from the same quarters as your attack - who are often the same private sector blowhards who cause many of the problems in the first place.

Far more public sector hating and damage comes from there than from the virtue signallers you (rightly) criticise.
