It's a matter of degree.  Many of us have used Windex with ammonia for years with no evidence of problems.  For example, soaking the parking pad with Windex and letting the head sit in it overnight is a standard way to deal with clogs.  It works.

Yes, I've had that also.  I think little "volcanoes" of binder and pigment build up on the side of the nozzle.  The parking pad is suppose to keep this soft so that the wiper blade can knock them off, but sometimes it doesn't work.  The under-head cleaning with a Windex (with ammonia) soaked bias tape had taken care of these deflected nozzles issues for me in the past.
