It is this lack of clarity (published limits) that scares many of us. It basically says that we won't know when we'll be cut off or shut down, but we'll find out when it happens! So if we build something that becomes wildly successful, we could suddenly be in a world of hurt if our site is deemed too heavy and we're throttled or worse. It would be like Pokemon Go - big explosion, lots of tiny pieces, customers gone. I urge you to have some kind of professional plan with guaranteed tiers. Otherwise, only naive people or people who really don't care about the future will use it (outside of the prototyping case everyone else is mentioning). On the other hand, it would be the perfect tool for someone on upwork or the like to do a gig ultra fast, leaving the client to deal with all the future pains. But since most projects end up not huge and successful, that might be just fine!
