Hooooly Cow!
I started reading this, then I started laughing, then I got bored with it and jumped to the last page... y'all still talking about the control levers on Stihl saws... unbelievable!

If you have a preference, if you like one brand over any other... no problem, who here doesn’t to a lesser or greater degree? I think you went wrong by using the “design flaw” argument though.
First let me say that I've owned and used many different saw brands and I prefer the Stihl Master Control Switch. Why? Because I NEVER have to look down at the saw to operate it, grasping the handle and/or throttle is a reference point for the hand, thumb is positioned perfectly even with heavy gloves. The positive stops (unless you force it) allow setting exactly where you want it (never having to look down at the saw). On - Off - Choke - Half-Choke - Idle - Fast-Idle - Kill - all done while never looking at the controls. Actually I think it's a rather good design, and if they tried to reinforce it to make it idiot proof (so you couldn't force it past the stops, bending springs, etc.) it wouldn't operate with the same (relatively) light thumb pressure, especially the up-flip.
1) Grab handle, press throttle, push down with thumb - full choke
2) Grab handle, press throttle, push down with thumb, release throttle, flip up with thumb - half-choke with fast-idle (blip throttle and you're at run position)
3) Grab handle, do not press throttle, push down with thumb - run position
4) Saw running with hand on handle, flip up with thumb - saw kills (I really like the ability to "KILL" the saw with heavy gloves while never compromising my hold/control of the saw or taking my eyes off the bar/work and it can be done in a split second even at full throttle)
All controls, on anything, are a compromise... make it idiot proof and it won’t convenient, make it too robust and it won’t be quick and easy, make it with too many parts and it’s prone to breakage, etc, etc., etc. The argument that someone (homeowner or professional) shouldn’t have to read the manual to use the saw, or clean the air filter, and that makes the “control” a design flaw is ridiculous. If something gets mucked-up because the user didn’t take the time to learn, and/or forces something... Well that ain’t a design flaw; it’s just plain operator error, period. C’mon, we’re talking about a power tool capable of removing your leg in a blink-of-an-eye... anyone that doesn’t take the time to learn how to properly manipulate controls and maintain the tool before using it is a fool (homeowner or professional), but that’s just my opinion I guess. I can tell you that in over thirty years of use I’ve never managed to muck-up the control lever(s), knob(s), or switch(s) on any saw, including the Stihl flavor.
This whole thing reminds me of the chokes on autos. Back before fuel injection, or even automatic chokes, autos had manual chokes. One style required that you press the throttle while engaging the choke because the choke “control” didn’t have the leverage to overcome the throttle return spring; failure to press the throttle resulted in a stretched cable or bent choke plate. Another style used a less-powerful return spring and a leverage system that would also set the throttle with the choke; the dangerous draw back with the weaker spring was that the throttle would stick open if the carb/linkage got dirty or during icy conditions. Another style used the powerful spring and a complicated leverage system that was prone to break just when you needed it most; users learned to open the hood in extreme cold and “hand engage” it first start of the day. And yet another style just used a separate control to “set” the throttle; requiring close attention or the engine would hopelessly flood. Everyone had their preference, and everyone thought the others were flawed in some way - they were unable to see the “flaw(s)” in the system they preferred. AND they all found the new-fangled, carb mounted, automatic choke systems to be a answer to a problem that didn’t exist - many never got the “hang” of “setting” the automatic choke, calling it a “design flaw” and just retrofitted their autos with manual chokes. It never occurred to them that they just weren’t taking the time to properly learn how to use the new system(s).
If you don’t like the “control” system on a particular brand of saw that’s fine - go with what you prefer. But if you muck-up the “control” because you did something to it beyond its design limit... well, that just flat ain’t a “design flaw”; you just plain screwed-up. Same goes for having to put the choke lever down before removing the air filter cover - no different than having to put your 4x4 in neutral before shifting into low-range... It-is-what-it-is.
