Well, in the most trivial and banal sense possible, it is: there's now another message app that wasn't there before.

I tried to unpack why this phrase is overused. I think it is because it's one of a few things that both sounds lofty when used in a pitch, and wiil always be true.

It's also a great dodge of considering the type of change (changing the world for the better or worse?) or of that change's magnitude (substantially changing the world, or just a little?). To some of a crowd, having heard the above, they will assume things about "changing the world" that may make further probing on those points at a high level sound like duplicate questions, and thus surpresses the chance of getting them. Useful for someone trying to peddle crap.

I only really see it used on potential employees, rather than potential customers. It sounds better than the more-correct 'come and sacrifice your best years on this pointless app that might make me rich but probably will crash and burn like all the others'.

That's definitely something which you can tell employees if you're making an app like that, but it's tolerable to use on customers too, in a pinch.

They probably won't believe you, but it's better sounding than nothing when features and tangible results are sparse.

And hey! When all else fails, it's at least guaranteed to not be false advertising.
