Also many of the things you complain about would be solved if you learnt to use your keyboard instead of using mouse gestures.
I use a large Wacom tablet in touch mode much of the time. It works pretty well with gestures for left click, right click and left drag but you do end up needing alternatives for right drag and middle click and drag because you run out of fingers. That's an adjustment for software like Unity or Blender that use them in their default control setups in Windows for actions that are not suited to keyboard (like camera control).
And then if you're using libinput instead of synaptics, which is the default on most distros now... just forget about it, because whatever you need is simply not implemented yet.
Using Linux on the desktop is a self-inflicted wound, and I can't believe this guy would write such a post saying that "trackpads sucks" when he uses Linux. Doing that is at best dishonest and at worst malicious.
Besides that there is an app Touchegg that lets you do more with the touchpad. But I haven't bothered using it because I am pretty happy with my setup.
So, yes, it's a nightmare.
