"obscurity isn't security" is true enough, as far as it goes, but is just not that far.
And "put the bugs that won't be fixed soon on a billboard" is worse.
The super naive approach is ignoring that and thinking that "fix the bugs" is a thing that exists.
Sure, in maybe 1 special lucky case you might be empowered. And in 99 other cases you are subject to a bug without being in the remotest control over it since it's buried away within something you use and don't even have the option not to use the surface service or app let alone control it's subcomponents.
Google does contribute some patches for codecs they actually consume e.g. https://github.com/FFmpeg/FFmpeg/commit/b1febda061955c6f4bfb..., the bug in question was just an example of one the bug finding tool found that they didn't consume - which leads to this conversation.
