Do compound machine exercises cause tendonitis even though multiple joints are used?

Compound-joint exercises distribute the stress over multiple structures and don't cause connective tissue injuries, while machine isolation-type exercises stress a limited number of joints and produce un-moderated stress focused on single joints.

Do compound machine exercises cause tendonitis even though multiple joints are used?

Give me an example.

[Squat1]

I presume that compound machines that move in a fixed i.e. plate-loaded isolateral row would cause joint issues.
However, the seated cable row I think would probably be okay albeit it uses less overall muscle as the stabilization is not present.

I don't know what a plate-loaded isolateral row is. Seated cable rows won't produce tendonitis, or anything else for that matter.

Maybe just do chins.

Could it be true that fixed plane compound machine exercises are troublesome for the rotator cuff muscles?

The link states that these machines are based off human movement.

I have seen an article that state that Smith machines are not good for the joints as it does not permit lateral movement.Should I Use Smith Machine or Regular Bench Press? - Major Fitness
