In my opinion, if people play your game a way that you did not intend, you have failed.
Emergent gameplay. IMO a game should only be a platform with which players gather in order to have fun and share experiences.
Skiing was not deliberate in Tribes, but it became a widespread strategy.
Rocketjumps weren't deliberate at first, but an artifact of the physics engines of numerous games.
The Legend of Zelda: A Link to the Past is a buggy mess, but players have found a way to manipulate these bugs to create some crazy awesome speedruns and challenges.
Super Mario has a ton of glitches which are still being explored to this day making for some really bizarre ways to play the game, and with Super Mario Maker, Nintendo has preserved these bugs to make the extreme glitching community able to make challenge maps.
The only failure possible is if your game utterly fails to be fun for a significant majority of interested players.
Players are always going to violate your expectations. You aren't making an ant farm. Let your players run free with the tools you give them, and occasionally look at what they are doing and figure out how to make their fun more fair and also how to enhance their fun. Bugs sometimes make excellent features.
That's not meta though. That's just bad design.
If your game is rock, paper, scissors, and you remove rock, people will naturally pick scissors because it cannot lose anymore. As a consequence of how you've designed the game, people alter how they play it.
If you're actively trying to control and alter the meta as a designer, I feel this is the sign of a bad designer. If people are exploiting bugs and you fix them, that is one thing, but if you go around removing or changing things just because you do not like how people play, that is something else entirely.
Best example would be LoL vs DotA 2.
LoL has an incredibly forced meta that has not changed in a long time due to the developer interfering constantly. It's games tend to be long, boring and very little happens. It's esports scene is a joke that is entirely run and funded by Riot (it's basically like wrestling, it's not a real sport and everyone knows it's fake, but they watch it anyway).
DotA 2 however, is balanced around hard data. If a hero wins 55% of games, it gets nerfed. If another loses 55% of games, it gets buffed. As a result it's meta is constantly changing, and it's esports scene is not only fun to watch (usually, except those boring metas), but has some of the biggest prizes in video gaming events anywhere because the players love this stuff.
Balance the game, don't dictate how people should play it.
