People with capital subsidising basic services is not a good thing because pensions are so widespread - the subsidy is essentially coming from the same people taking the ride in the first place, just via an incredibly high overhead and roundabout trip!
It makes a very convincing argument that VC is a bad investment vehicle for pensions, but I can't draw the line from this article to pensions are subsidizing basic services.
Certainly with Uber, it's largely Saudi Arabia right now that's subsidizing riders. That is a very circuitous path for the Saudis to benefit or enrich their subjects, but everyone else in the uber world is benefiting.
