"Words still mean things" is not an argument.
This can be a 'breach' by many of these definitions.[0][1][2]
You're basically saying, "Words only mean the things that I want them to mean, and if you try to use them a different way than I approve, then I will use this meme to try to shut you down."
Words fluctuate in meaning all the time. This may very well be the beginning of a new definition for breach, i.e., a social data breach, for example.
But we don't even have to go so far as to claim that this is a new meaning for breach. Any of these old definitions contains sufficient meaningfulness to make "Facebook loses control of data to unauthorized breach" perfectly intelligble.
