We added code to uncheck the boxes for dumbasses like you that accidentally checked them. If there was ever anything wrong with our code that caused them to be checked as you claim you could find an archive of it as proof. You can't do that because there was never a fault.
Whether Freebitco.in was intentionally causing this issue is debatable but there was definitely a bug that affected the website which caused jackpots to be checked without the user activating them. I wrote a complaint through the site's contact form when this happened to me a few years ago and never received a response. I also found
this post from a user that describes the exact same problem. I suspect the issue was caused due to browser compatibility issues since I only had the problem on old versions of Android and Linux that were no longer supported by Chrome and once on Brave desktop browser which is known to be buggy. Since nobody ever replied when I messaged the website I did not bother keeping any logs with definitive proof that this bug was occurring, but after seeing several complaints and from personal experience I do not think it's fair to say it's just dumb ass people accidentally enabling the jackpots.
