In the deleted tweets, he was using "breach" in the narrow sense of computer security, basically saying "my team didn't mess up, we didn't get hacked". There are two problems with that: 1) That view is already too narrow for practical security engineering. It's not enough to have a technically correct solution, you need to consider the entire product to ensure that it has the expected security properties in the way it's actually used. 2) Worse, it ignores how the message is going to be interpreted outside of the computer security field, which is especially important when the company is under political scrutiny. For a C-level executive, it seems like an unfortunate lapse.
