Ah, but when you're little, if each misstep annoys a few early users who hit a dead-end with your project, the longer-term reputational damage is trivial. You've still got 99.999% of the TAM (total addressable market) that is ready to be charmed by something new, with no negative vibes in their mind.
As you get bigger, serious numbers of people get annoyed at dealing with a company that keeps inviting us into the Roach Motel of doomed products and features. Big case in point was Google's spree, a few years back, in terms of launching big new services/features that soon afterward got shut down. Great training ground for ambitious PMs; miserable user experience.
Somewhere between the death of Google+ and the demise of Google Hangouts, even folks like me began thinking: Why should I engage with new Google stuff if it's likely to be blown up in a few years, leaving me with buried IP from whatever I tried to do?
