I'm sorry but if your product can be easily copied by Facebook, you don't really have a product.
There was once a time when video chat was novel, but now since the technology is "done", there is nothing hard about developing these services from a technical perspective. Handling scale and various other things with these products used to be a challenge but now we have the cloud, API's and a mature ecosystem. The world really doesn't need more of the same kinds of communication apps, it all just becomes a gimmick and less of a utility.
So, most of these products will be successful based upon other factors -- such as the cleverness of their marketing, or whether or not they serve a niche that is lucrative enough and underserved enough on which to build a successful business, but not large enough to attract the attention of one of the goliaths.
The one advantage startups have over large corporations like Facebook is their size and speed at which they can move. Engineers at Facebook, like any large tech company, are encumbered by substantial process, political forces, and a reluctance to try new ideas. Your typical startup employee is also far more motivated than an engineer who just wants to be given their daily JIRA tasks. To be honest, why does a single app need a team of 500 (frontend) engineers in the first place? When a tech company gets large, it becomes more about business than technology, anyways.
So, it doesn't come as much of a shock Facebook is turning to the startup world to source their ideas and duplicate them, which is why I advise all my friends to steer clear of any of these "we're a better way to share/video chat/chat/message/communicate" startups. Only go to one if you have some burning technical itch. The one exception is if the founders aren't totally delusional and the company operates more under the impression of just getting an MVP built, with the idea of shopping it around to be acquired in short order. And in this case, know exactly how long that's going to take, take no VC funding, have no delusions of grandeur and as an engineer know exactly what cut you're going to get when the thing gets sold. I've only seen this work if the founders know someone at the big company and the thing has all been basically pre-arranged though.
> Most things can be easily copied if you throw enough money and developer hours at it
I would argue everything can be copied from a technical standpoint (excluding patent issues.) Marketing and user adoption may or may not be successfully copied though.
FWIW, they did pose a competitive threat to Facebook, forcing FB to add features like choosing which groups of "friends" to show a particular post and letting people see public posts of people who aren't bidirectionally connected. If Facebook had refused to adapt at all, G+ might have grown more significant.
