It's especially limiting for those on a shoestring budget with great
ideas, and the commercial vendors lose out because of this: You have
this great idea for an app, you see great technology in a commercial
database, but you can't afford the unlimited connections licence.

around again and notice the Open Source alternatives. What to do...
What to do... You incorporate the Open Source database, commercial
vendor loses a potential client. Maybe, just maybe, in the future you
can then afford the commercial database: Do you switch to the
commercial/supported product? Do you risk changing the infrastructure
