I think there is a lot to be said about the shortcomings of the Android world in how Linux Kernel updates are trickling down the whole foodchain (or rather: are not). BUT: This particular episode is a very bad choice for your argument. Cause in this case the bugfix in question was never ported back to any regular Linux LTS version, while it actually was cherrypicked for the Android Common Kernel (branches 3.18, 4.4 and 4.9). Now why that fix never made it in most vendor kernels (besides a few like the one in the Pixel 3 that is based on 4.9) is a good question. But at the same time there is the reality, that everyone focusing on the upstream LTS kernel would have never gotten the fix.
