Take Firefox’s 1542044, where the dark mode theme colors aren’t exposed when they should. The patch has been up for 4 years.
Or, take this, which is part of a series that added Doxygen parsing to clangd, a language server. It was left unreviewed until late 2022, the patcher went in conversation with the reviewer, but then met radio silence again, long enough to the point where the patch-reviewing service shut down. Clangd currently has only 44 open PRs to review, though it uses the same issue tracker as llvm for some reason.
Aren’t we paying them to do all this?

That’s 250 million for development. That chart is also in thousands.
And this is somewhat beside the point, but Lunduke is a conspiracy nut job and rather looking for an egregious story than the truth. Whatever he interprets into these numbers, you should double check it.
