There is no reason to believe that money would actually solve the issue, and maybe even exacerbate it.

The log4j issue is product debt, similar to the sqlite fts tokenizer exploit, and a lot of the openssl exploits, features that are rarely used, and are in the codebase for "no good reason" (from the majority of user's standpoint)

I think the way to make for those things to happen less, is in fact, to code less, and make more small things rather than one giant bloat of features. Paid or not paid, security becomes near impossible after certain amounts of interconnected components.
