In one case, the same person did the same thing to us twice in a row - interviewed, got an offer, then got "counter offered" from their existing company the next day. Pretty confident that they're just interviewing as a negotiating tactic.

But honestly, in general, if someone interviews around then decides to stay at their existing company for more money, they're probably not the folks I'd be likely to hire regardless. They're not looking for new learning opportunities, or new ways to grow, they're maximizing for some other value structure. And best of luck to them with that, I'm sure they'll find plenty of companies where those values are the expectation and norm.

You're "playing the game", but I build teams out of folks who aren't game players. :)
