I know folks that are very privacy conscious that are used to and hate cookie popups and will treat formbricks as just another cookie popup and will adblock, download a blocklist, or use a PiHole to remove intrusive popups automatically.
Also since it can be self-hosted, it can be served from the same domain as the application within the survey. We also see the surveys as part of the application and a necessary part for the maintainers to provide their service.
they will do the same without javascript then, why would a privacy conscious person reply to a survey - the opposite of privacy?
