Well, it depends on many factors. Firstly, IMHO, the comparison with Oracle doesn't quite fit. A code analyzer is not a design/infrastructure dependency like a database. You can stop using the code analyzer and your software will continue to build.
Anyway, to give you an anecdote.. My current work is in a niche industry where "simple" software is often very expensive and prices are never displayed ( $10,000 per seat). What I've found is that often times, the company itself would let me know that their software is not a great fit for our company because I contacted them and explained the use case. Other times, not displaying the price allows them to give a price cut to smaller startups and "tax" larger companies for whom the price is negligible.
