This feels a bit like those “FOR TOBACCO USE ONLY” signs at headshops who sell bongs.
In an industry with plenty of founders who have said one thing and then repeatedly done another I don't think it's being jaded to be cautiously pessimistic. If the market for RescueTime ends up being primarily spy tech, then it's naive to think that's not the direction it will go.
Tech is also an industry that has let its naivety blind it to some rather obvious perverse use cases.
You may prove this all wrong becoming a legendary founder who holds the line into perpetuity against selling your SaaS as spy tech even if that's what the market wants. That would be an amazing story to watch unfold.
