of course, SetupBuilder is still supported and we are working hard on the soon coming SetupBuilder 2022. Where do you see open (not answered) support threads here?

But we did not receive any message from "instrumentally" via our contact form. Did you click the "Send Message" button and did you see a "submitted" message? BTW, you can always contact us via support [at] lindersoft [dot] com and you even have my direct e-mail contact from previous support requests.
