There is a material difference between all of those examples and Intuit though. It is normal for governments to use incentives to drive their policy objectives. If they want to incentivize home ownership for example, the resulting increase in complexity of the tax code may be a reasonable trade off. Intuit is just trying to get a government guarantee that their business model will continue to exist, without their being any positive public policy angle to compensate for the negative externality. In other countries free tax filing is the norm, because although they have the same types of incentives to promote policy objectives, the government has not allowed themselves to become captive to someone like Intuit. For example, I have filled my taxes in myself (for free) in the UK for about 20 years now. It used to be a (simple) paper form. Then around 15 years or so ago it changed to be web or paper (your choice) and now they strongly incentivise web over paper. For the last 2 or 3 years all the important details of my income and pension are already filled out automatically from the record they get from my employer and I only need to fill in the capital gains and charitable giving parts of my return.
