On your third point, I have few perspectives to offer. The first is that because the companies you listed are out to make a profit, it is easier to understand how your data will be used. The very fact that the government has less clear motives is what makes their collection of data more unsettling. Second, when a company is driven by profit and loss, they have incentives to secure data because the inability to trust a company with your data will lead to fewer customers. Sure, your data may get out in an attack, but over time, to the extent its valued by the consumer, more secure companies will stick around longer than those that are insecure. If the government loses your data, some people may be fired, but agencies as a whole will stick around and keep conducting business as usual. Third, along these same lines, a government data store means multiple sources of data collected into one target. To those with malicious intent, it seems logical that attempts to take that data will be more frequent. Finally, those, familiar with the school of public choice, will recognize that government actors are out to "make a profit" just not in the traditional sense. As a former gov employee, I can tell you that while there are policies in place, the fact that many gov employees transition to private sector and vice-versa, data collected will in some way be used for profit and likely by someone you did not give permission to, as is the case with Amazon or Verizon.
