Because nvidia optimus drivers are not open sourced and a huge PITA in some linux distros/desktop environments who wish to stay as FOSS as possible.
Not a problem on desktops since they don't have optimus but on laptops without a proper optimus implementation for linux you'll end up with your 1660TI or whatever running at full blast with just your terminal opened, killing your battery in no-time and turning your laptop into a frying pan.
That's why linux devs prefer no nvidia dGPUs on their laptops.
