If I had to guess, they're probably referring to the way that certain devices broadcast their APIs to external services. A lot of them have no intention of allowing open access to APIs (e.g., my mini-split controller requires a slight hack to get it connected to HA). That is, the flakiness isn't due to HA updates breaking connections or an unstable server, but rather manufacturers designing closed and/or brittle systems. Try as they might, the HA authors and surrounding community can only do so much for such devices. Also, I believe the word you're looking for is 'wary' (as in, to be skeptical or suspicious), not 'weary' (as in, to be tired). :)
