Cool concept, but morally dubious. You're basically using people's electricity in the background without people knowing, not unlike bitcoin miner malware.
It's extra work for website owners to build/test/maintain opt-out functionality. Have you considered offering a pre-built opt in/out widget which can be re-styled and integrated easily?
Or you could even just provide website owners with a "global opt-out" URL that they can stick in their footer.
We don't want anyone on the platform who isn't aware/comfortable with it. Our instructions to the websites (when they join) are to create a link to the opt out page. I supposed it could be a direct opt out
What do you mean? Unused cycles makes no sense. I'd be really annoyed if my laptop's battery life drops from 5 hours browsing the web to 1hour because it is running at 100% all the time due to this.
