I have a mix of products and no issues with them.
The FTDI thing was sorted out a while ago now.
CH340's work just as well on clone Arduino and that has nothing to do with FTDI
Your USB issues could be anything but you have not given enough information for anyone to try help you.
Lots of drivers don't have uninstallers but you can uninstall from DEVICE MANAGER very easily.
I know a few bits of hardware and software that make removal a PITA not least of all Apple and Canon and Epson so its not like its deliberate.
Some Arduinos have FTDI and some don't. There are a few USB interface chips available and so it can often depend on where you buy your Arduino.
From my perspective its about as open as you can get if you disregard the litigation between Arduino and Arduino LOL
So is your post a rant or a request for help...its hard to tell
Oh and FTDI will NOT destroy an arduino...sheesh such nonsense.
