I will be the first to jump in the pool and give my opinion.
One the link never came up but I didn't really need it to.
First as you well know never prune determinants or dwarfs.
Second I never prune anything but the leaves that are close to the ground, this is where you get most of your problems.
I dont grow for giant tomatoes so in that respect I dont prune.
In my interpretation a sucker is something that comes up from the stump and robs nutrients from the main plant like what is called a tiller with corn.
The natural branches that happen along the plant is its natural way of growing and therefore opportunity for more tomatoes.
Where I live if I started pruning all I would do is limit the amount of fruit I got because it would take longer for the plant to produce more blooms.
By this time it would be too hot and the later blooms wouldn't set.
During the growing season I will any and all suspect leaves and branches that dont look right.
I am not saying this is the right way or only way just my way.
