The nose pitching up is not a problem in and of itself; it's only a problem when it causes the angle of attack to approach a stall condition. You're not going to get that just from increasing thrust during level flight.
Actually, increasing thrust does cause a pitch up on this model of aircraft. Go to YouTube and look for Mentour Pilot. He has several videos covering a wide array of aircraft questions. He has a few about the 737 MAX, at least one about pitch changes caused by thrust on various aircraft, and why the MCAS system is considered necessary for this particular aircraft.
From my own other reading, it appears that the greatest contributor to the MCAS system "software failure" is that the system relies on the input from one sensor (that is known for having an unacceptably high rate of failure) unless the aircraft purchaser paid for an upgrade that can include input from another sensor. No matter how good the code might be, crap input from a failed sensor is going to result in crap (read: fatal, unless your pilot knows how to override it) output. In the latest incident, the pilots had no training on how to override the MCAS system.
