You seem to misunderstand that thread.
If you do a stock install of Ubuntu you'll have very many, showstopping, errors.
If you use a custom script that forces a custom bootloader, custom kernel, and a bunch of other fixes, you end up with a machine that still doesn't have headphone audio and some problems with bluetooth.
A self-defeatist attitude won't make this more comfortable. If you don't like that Windows 10 is full of ads and spyware, the time investment to get this laptop working seems pretty small in exchange for a better OS. Throw in a little extra time to get these fixes applied in the form of patches to the relevant projects. If everyone gave up because they can't put a few minutes into troubleshooting and tweaking their setups, Linux will never grow to the threshold necessary to get vendors to support it OOTB.
How weaselly. His conclusion is plain to see:
"The result? Ubuntu still doesn't fully work on that particular machine"
