> which I need for work purposes, so I had to buy a new MacBook Pro. I certainly didn't want to drop all that money right now.
I can sympathize with being frugal. That said, if you're buying a laptop for work, I recommend both financing it and depreciating it on your taxes, if that's an option for you. It's a cost of doing business, and many tax codes treat computers as depreciable assets. In fact, in the U.S., the tax code has a 5-year depreciation schedule for computers - less than the support lifetime.
As for the security updates question, if you have information that Catalina is lacking a critical security update, I'm sure Apple would like to know about it and fix it. They care a lot about this stuff. The article you posted complains about a lack of transparency as to the "why" certain patches aren't backported, but it doesn't declare that there are active security vulnerabilities in those versions, either.
