Then why do I have to disable my internet connection to get Q to open? The only reason is Q is being a PITA and trying to convince you to spend more money with them. There is no technical reason it must be so.
Among the "not a single facts":
"They are making continued use of the non-subscription version difficult, so we buy a subscription based version."

Once again you are making false statements.
Quicken is not "MAKING continued use of the non-subscription more difficult ....".
There is no intention on Quicken's part to cause expired versions to stop working (other than the aforementioned loss of downloading and support, which are intentionally ended when the "subscription" ends).
The "technical reason" for your problem is way more likely to be attributable to human error. A software bug, or (as suggested in the discussion Sherlock pointed you to) something wrong with the server Quicken needs to contact when it opens.
[You do realize that since about Q2014, Quicken must authenticate you as a valid user, by verifying your "Quicken ID" ... right? Quicken does that by communicating with a server on the internet - hence the need for a successful internet connection to that server.]
Other expired versions of Quicken (versions that existed prior to the introduction of the subscription version have also experienced problems from time to time. When those problems could be determined to be Quicken problems and those problems prevented Quicken users from using the product as Quicken intended ... Quicken fixed the problem ... even when the problem version was no longer supported.
There is no such thing as bug-free software, or perfect human beings. Your attempt to pretend that Quicken is intentionally creating problems, or intentionally not fixing problems, is not supported by a shred of evidence.
You should also understand that there is a very good reason for "support" ending for expired Quicken versions (every version since at least Q2004 expired after 1 to 3 years). Providing support costs money and expecting something for nothing is a dead-end presumption. Eventually Q2016 will stop working due to changes which Quicken will not correct (incompatibility with newer operating systems, for example).
Up until this morning, I had Q2016 R18.4 installed and it was working with no problem. This morning I installed release 19.5, and it too runs with no problem.
So either Quicken fixed the problem while you were wasting time falsely attributing unethical behavior to them, or there is more to the problem than so far posted.
