I get where you're coming from, and that it's no guarantee of safety, but less obvious resistance like malicious compliance, strategic incompetence, 'accidents', and 'everyday resistance' can be a very effective strategy.
As you yourself say, it may change who they go after first, allowing you to fly under the radar longer and fight longer while undetected. Then again, letting people know they're not alone, is also important. So being loud also has its merits.
Of course, I would never be too concrete about all this on the internet, for obvious reasons. I'm also not stopping anyone who wants to take a more brazen route. In some cases, when some campaigns go viral, it has also been effective.
Put simply, there are advantages to appearing unthreatening, stupid, and boring.
